CachePix and Lightroom Classic: a catalog you can carry

Lightroom Classic is a full photo editor and catalog on one computer. If you want a Lightroom catalog alternative for browsing, not editing, CachePix is a companion: it catalogs the same folders and syncs a searchable catalog to your iPhone or Android phone over your local network. Your photos never go to the cloud.

The short version

As of October 2026, Lightroom Classic is a desktop app for Windows and macOS: a full editor plus a catalog. To see Classic photos on a phone, you add them to synced collections, and they appear in Adobe's separate Lightroom mobile app through Adobe's cloud. If you want Lightroom mobile without the cloud, CachePix is a different route: its catalog syncs to your phone over your local network.

This isn't a swap. CachePix has no pixel editing, no facial recognition and no video support. What it gives you is a searchable catalog of your archive in your pocket, with no collections to pick. Keep editing in Classic, and point CachePix at the same folders.

What CachePix reads from a Lightroom workflow

CachePix reads what's written in your files, not what lives only inside Lightroom's catalog. That one fact decides what shows up.

Lightroom Classic edits nondestructively. By default, edits and metadata are stored in its catalog rather than in the files. According to Adobe, Classic can write metadata into JPEG, TIFF, PSD and DNG files, and into sidecars for raw formats, if you choose to. It's off by default.

What CachePix picks up

Once the metadata is in a JPEG, PNG or WebP file, or in the XMP sidecar next to a RAW file, CachePix reads keywords, caption, headline, title, city, state, sublocation, creator, event and categories, plus people from the "persons shown" field (XMP PersonInImage). Per Adobe, names you confirm in Lightroom's People view are saved as keywords, so they arrive in CachePix as keywords.

What it doesn't read

  • The .lrcat catalog file and your Lightroom collections.
  • Star ratings and color labels set in Lightroom.
  • Develop edits. RAW previews come from the camera's embedded JPEG, so your Lightroom edits to RAW files don't show.
  • Camera, lens, exposure and GPS data, from any app.

Check your formats. CachePix catalogs JPEG, PNG, WebP and 15 RAW formats (CR2, CR3, NEF, NRW, ARW, SR2, RAF, ORF, RW2, DNG, PEF, SRW, X3F, IIQ, 3FR). HEIC and TIFF photos are cataloged and searchable, and previews for them are coming. Video isn't supported, and PSD isn't on the list.

CachePix vs Lightroom Classic side by side

Lightroom Classic cells follow Adobe's own pages. CachePix cells describe desktop 0.2.1 and the 1.1.0 phone apps.

Lightroom Classic details per Adobe's website, as of October 2026
FeatureCachePixLightroom Classic
Desktop appMac with Apple silicon (M1 or later) on macOS 12 or later, and 64-bit Windows (x64). No LinuxWindows and macOS, no Linux. Adobe lists macOS 14 Sonoma or later (Intel or Apple silicon), and Windows 10 (22H2) or Windows 11 (23H2 or later)
Phone appYes: iPhone and iPad on iOS 18 or later, and Android 9 or later, covered by your CachePix planPartly: Classic runs only on a computer. Synced collections appear in Adobe's separate Lightroom mobile app
What reaches the phoneA thumbnail of each cataloged JPEG, PNG, WebP and RAW photo, plus HD previews for a capture-date window you choose, synced over your local networkOnly photos you add to synced collections, through Adobe's cloud
Photos in a vendor's cloudNo. Your photos, previews and catalog never leave your own computer and phone. CachePix's only online service is your account: email sign-in, the plan check, and Stripe billing in your browserPartly: originals stay on your drives. With sync on, smaller Smart Preview copies of photos in synced collections go to Adobe's cloud
Browse with the drive unpluggedYes, on your computer and your phone, from cached thumbnails and HD previewsYes, on the computer, per Adobe, for imported photos. Smart Previews let you keep editing
EditingNo. CachePix doesn't edit photosYes: a full nondestructive editor that reads raw files from most cameras
Facial recognitionNo. People names come from metadata in your files, or names you type in CachePixYes, per Adobe: the People view suggests names and saves confirmed names as keywords
Finding photosOn the computer, one search box across 13 fields, from filename and people to keywords, caption and city. The phone searches filename, people, keywords and caption, with filters. No camera, lens or GPS searchKeyword, EXIF, IPTC and XMP metadata, with filters by keywords, camera and lens data. Adobe's own comparison describes finding photos in Classic as "manual keywords"
Writes to your filesCataloging never modifies, moves, renames or deletes your files. CachePix writes metadata only when you edit it, and only the fields you changed, as standard XMP in the file or in a sidecar next to RAW filesNot by default: edits and metadata stay in its catalog. Writing XMP to files and raw sidecars is optional, per Adobe
VideoNo. Video isn't supportedPartly, per Adobe: imports, views and trims camera video in the Library module; videos can't be edited in Develop and don't sync from Classic to Adobe's Lightroom cloud
Server to runNo. There's no server for you to install or runNo. It runs on a single computer
Sign-in and license checkEmail sign-in. CachePix checks your plan online at least once every 14 daysPer Adobe, activation needs an internet connection and an Adobe ID, and the app attempts to validate the license every 30 days
Price and trial$4.99 a month or $29.99 a year after a 14-day free trial (card required), or $99 once for Lifetime. No free tierPer Adobe's US site: Lightroom (1TB) plan at US$11.99 a month (annual plan, billed monthly), or Photography (1TB) at US$19.99 a month (annual plan, billed monthly). Subscription only, with a 7-day free trial and no free tier

Adobe's prices vary by region and billing option. As of October 2026, the Lightroom (1TB) plan also includes Adobe's cloud-based Lightroom apps and 1 TB of cloud storage, which CachePix doesn't offer. Because Classic keeps originals on your own drives, its price doesn't grow with your library. Neither does CachePix's.

Lightroom Smart Previews vs a phone catalog

Lightroom Smart Previews and CachePix previews are both smaller stand-ins for your originals. They're built for different jobs.

Smart Previews are for editing. According to Adobe, they let you keep editing in Lightroom Classic while the drive with the originals is unplugged, and the edits apply to the originals when you reconnect the drive. With sync on, Classic uploads Smart Preview copies of photos in synced collections to Adobe's cloud, and Adobe says they don't count against cloud storage.

CachePix previews are for finding and looking. Your computer keeps a 512px thumbnail and an HD preview (2048px by default) of each cataloged JPEG, PNG, WebP and RAW photo. On the phone, HD previews download automatically for a capture-date window you choose: 30 days, 90 days, 1 year (the default), 2 years or All photos. Full-size originals stay on your drives.

The phone side is smaller than you'd expect. On the library we measured, 190,566 photos (885.66 GB) in two folders on one external drive, thumbnails took 8.03 GB on an iPhone, and HD previews add about 349 KB per photo. Here's how much space it uses on your phone, with the method.

Lightroom photos on an external drive

Per Adobe, Lightroom Classic catalogs photos on internal or external drives, though the catalog itself can't be stored on a network drive; what a Lightroom catalog is covers the details. CachePix can catalog the photo folders on that same drive and sync a catalog of them to your iPhone, iPad or Android phone, so you can view external hard drive photos on your phone with the drive unplugged.

When Lightroom Classic is the better pick

If editing is the job, Classic is the tool. Adobe's release notes list version 15.6 (September 2026) as the latest as of October 2026.

  • You edit RAW files. Classic reads raw files from most cameras, processes them and can convert them to DNG.
  • You want names suggested for you. Per Adobe, the People view suggests names across your catalog. CachePix has no facial recognition, by design.
  • You search by gear. Classic filters by camera and lens data. CachePix doesn't read either.
  • You keep video with your photos. Per Adobe, Classic can import, view and trim camera video. CachePix doesn't catalog video.
  • You're on an Intel Mac. As of October 2026, Adobe's requirements include Intel Macs. CachePix needs Apple silicon.

Lightroom catalog alternative: when CachePix fits better

If you want a Lightroom alternative for organizing and finding photos, CachePix fits when:

  • You want to browse your Lightroom photos on your phone offline, with no collections to pick. Each cataloged JPEG, PNG, WebP and RAW photo gets a thumbnail on the phone, browsable and searchable with the drives at home.
  • You'd rather keep previews out of any vendor's cloud. The catalog syncs one way, from your computer to your phone, over your local network.
  • You're finding, not developing. A finished family archive doesn't need an editor. CachePix is $29.99 a year after a 14-day free trial (card required), or $99 once for Lifetime.
  • Your Mac runs macOS 12 or 13. CachePix runs on Apple silicon Macs from macOS 12. Adobe lists macOS 14 or later for Classic (as of October 2026).

The full list of what CachePix reads, and what it doesn't do, is on the features page. For background, see what a Lightroom catalog is.

Use them together

CachePix doesn't open the .lrcat file, and Lightroom Classic doesn't need to be running. A setup that works with CachePix 0.2.1:

  1. In Lightroom Classic, have metadata written to XMP. Adobe's help pages describe automatic XMP writing and Save Metadata to File.
  2. In CachePix, open Drives & Folders, choose Catalog a Folder… and pick the folders or drive where your Lightroom photos live.
  3. Open Pair Phone…, click Turn On, and scan the QR code with your phone.
  4. After a keywording session in Lightroom, run Sync Search Metadata in CachePix. If a change doesn't show, use its Re-read every photo option.

Keep RAW metadata in Lightroom for now. CachePix 0.2.1 writes RAW edits, DNG included, to a new .xmp sidecar and can't reliably update an existing Lightroom sidecar. For RAW and DNG files, keep editing keywords and captions in Lightroom Classic.

Keep your own backups. Adobe lists cloud file backup as not included for Lightroom Classic. CachePix is a catalog, not a backup. It makes your archive findable. It doesn't make a second copy, so keep backing up your drives.

Common questions

Can I see my Lightroom Classic photos on my phone without Creative Cloud?

Yes, with CachePix, for JPEG, PNG, WebP and RAW photos. It catalogs the folders where your Lightroom Classic photos live, then syncs thumbnails, plus HD previews for a date window you choose, to your iPhone or Android phone over your local network. Adobe's own route puts only synced collections on your phone, through Adobe's cloud (as of October 2026).

Will CachePix show my Lightroom edits?

No. By default, Lightroom Classic keeps edits in its catalog, which CachePix doesn't read, so RAW files show as shot, previewed from the camera's embedded JPEG. JPEGs you export to a cataloged folder show up too. A JPEG with the same name, in the same folder as its RAW, pairs with it as one photo and becomes its preview.

Does CachePix read my Lightroom keywords and star ratings?

Keywords, yes, once Lightroom Classic writes them to a JPEG or an XMP sidecar (off by default, per Adobe). Star ratings and color labels, no. CachePix reads captions, city, event and other IPTC and XMP fields, plus people from the Persons Shown field. Per Adobe, names confirmed in Lightroom's People view are saved as keywords, so they arrive as keywords.

Is CachePix a Lightroom replacement?

No. Lightroom Classic is a full photo editor plus a catalog. CachePix doesn't edit pixels, has no facial recognition and doesn't catalog video. It's a companion: it catalogs the same folders, searches 13 fields from one box on your computer, and syncs a searchable catalog to your iPhone or Android phone, for $29.99 a year or $99 once.
