Fully open source gallery with no ads, tracking or unnecessary permissions. Tons of cool features and customizable colors, no internet access required, made with privacy and simplicity in mind.
Simple-Gallery (GPL-3.0) was my favorite FOSS gallery app until the project was sold to a shady company named ZipoApps in 2023. I forked it to keep it alive, FOSS and updated. This fork is not affiliated with Simple Mobile Tools, Fossify, or ZipoApps. Code contributions are very welcome :)
APKs are published on GitHub Releases

The original Simple Gallery Pro workflow, plus a new completely FOSS editor, OCR, AVIF/JXL, motion photos, 360° panoramas, and much more. Still offline, still FOSS and GPL-3.0
Edit
- Copy text (OCR) — Viewer overflow reads printed text and numbers on a photo and copies them. On-device PaddleOCR (PP-OCRv5) engine and model files. Nothing is uploaded. This adds ~20MB extra to the apk file but it's a handy feature I wanted to have.
- FOSS photo editor — Crop, rotate, resize, draw, filters, tone sliders, and text/emoji stickers. Tools stack in one session. Undo last tool (up to 3). No proprietary SDK.
- Editor stickers — 6-column emoji grid (arrows, markers, faces) plus More for the system emoji picker.
- Lossless JPEG rotate — Viewer rotate/save and editor rotate-only keep original quality and size. Save as no longer crashes on EXIF write.
- JPEG optimize — Native jpegoptim: lossless Huffman or lossy (default 85). EXIF kept; file replaced only if smaller. Batch from the grid.
- Video trim — Cut a clip to a start/end range and save it next to the original. Toolbar sits below the status bar.
- Save frame — Grab the current video frame as a JPEG from the viewer or in-app player.
- Collages — CAB on 2–4 photos: side by side, stacked, or 2×2.
Formats
- AVIF, JPEG XL, Ultra HDR — Grid, viewer, and “open with”. Animated JXL plays in the viewer. Wide-color display with a settings toggle.
- Motion photos — Play Google Motion Photos, Samsung Live Photos, and Micro Videos; save the clip as an MP4.
- 360° and video — OpenGL photosphere viewer (touch, pinch, gyroscope). Toolbar sits below the status bar. In-app player with speed, mute, long-press 2×, and exact seek.
- EXIF orientation — Viewer and region zoom honour the embedded orientation tag.
- WebP pinch-zoom — Animated and still WebP zoom in the viewer.
Organize
- Thumbnail stays with its file — A recycled grid cell no longer shows another file's thumbnail while the real one is still loading.
- Stacks — Optional RAW+JPEG, bursts, and edited copies in the grid, with a strip in the viewer.
- Folder tree — Grid, List, or Tree. Show hidden and Show excluded stay on until you turn them off.
- Scroll-back — Closing the viewer returns the grid to the photo you were on.
- Instant favorite star — Tap the star on a thumbnail or in the viewer; the overlay updates without a reload.
- Show filenames — Off by default. Settings → Thumbnails, or the label icon in a folder.
- Clean thumbnails — The favorite star overlay is off by default. Turn it back on in Settings → Thumbnails → File thumbnail style → Mark favorite items.
- Darker dark theme — Dark and Dark red backgrounds are
#111111instead of#2D2D2D. Existing installs are moved over automatically. - Favorites only — Overflow toggle to hide everything that is not a favorite. It is session-only, so other folders keep their photos.
- Properties — Works on the Favorites and Recycle Bin folders.
- Tags — Add or remove tags from the grid or viewer (tap × on a chip). Commas make separate tags. Search matches tag names.
- Duplicate finder — Scan a folder (or all) and delete extra copies. Overflow item sits above Settings.
- Android Trash — Optional MediaStore trash on Android 11+ instead of the app Recycle Bin. Favorites also write
IS_FAVORITEwhen the system allows it.
Private
- Locked folders stay hidden in Favorites, Recycle Bin, and widgets until you unlock.
- Strip metadata — Remove GPS or all EXIF from photos, or when sharing.
Motion
- Fluid viewer — Swipe down tracks the photo and springs closed or back. Open and back scale from the thumbnail. Viewer bars slide and keep the old gradient. Favorite, share, edit, and delete stay on the bar; the rest sit in a More sheet. Editor tools slide up from the icon that opened them. Grid tiles scale on press. Slideshow yields to a touch. Animator duration scale 0 uses fades only.
- Video end — A video that plays to the end does not resume at the end next time. Double-tap skip shows a short chevron.
- Hide and unhide — A second hide or unhide of the same file waits until the first rename finishes.
No nags
- No donation prompts.
