Squish vs DepthWeaver

Squish reduces any photo to an exact target file size — 200 KB, 500 KB, 1 MB, or any number you type — in a couple of seconds. Pick a photo, choose a target, save. That's it. HOW IT WORKS 1. Select a photo from your library. 2. Choose a target size: 200 KB, 500 KB, 1 MB, or enter any custom KB value. 3. Pick JPEG or PNG. 4. See the before and after file sizes instantly. 5. Save the compressed photo to your library or share it directly. Squish tries compression settings to find the highest quality that still fits your target. When adjusting quality alone isn't enough, it scales the image down as well. You get the best-looking file that meets your size limit. WHY USE IT - Attach photos to email that has a file size limit. - Upload to forms, applications, or government portals that require images under 500 KB or 200 KB. - Free up storage on your device. - Prepare images for web uploads, messaging apps, or anywhere with size restrictions. - Resize passport, ID, or visa photos to meet strict file size requirements. WHAT MAKES IT DIFFERENT No subscription. No ads. No account. No in-app purchases. Pay once, use it forever. Your photos never leave your device. Compression runs entirely on your iPhone or iPad, with no internet connection required. Nothing is uploaded, nothing is collected, and no server is involved at any point. Both JPEG and PNG are supported, in light mode and dark mode, with a layout built natively for iPhone and iPad. ABOUT IMAGE QUALITY Making a file smaller means giving something up — that's what compression is. Squish's job is to give up as little as possible: it keeps the highest quality that still fits the size you asked for, and shows you the result before you save. Reduce a typical photo to 500 KB and the difference is hard to spot at normal viewing size. Reduce that same photo to 50 KB and you will see it. The trade-off is always yours to make. COMMON QUESTIONS Q: How do I make a photo smaller than 500 KB on iPhone? A: Open Squish, select your photo, tap 500 KB, and save. It takes seconds. Q: Does it work on iPad? A: Yes. Squish runs on both iPhone and iPad, with a layout built for each. Q: Will my photo lose quality? A: Some, unavoidably — that's what compression is. Squish keeps as much quality as your target size allows. Q: Is my data safe? A: Completely. Everything runs offline on your device. No photo is ever sent anywhere. Q: Do I need a subscription? A: No. One-time purchase. No recurring charges, no in-app purchases, no ads.

DepthWeaver turns real-world depth into hidden-image stereograms. Capture a scene with the LiDAR scanner, generate depth from any photo with on-device AI, scan a real object with Apple's Object Capture, or load a 3D model — then watch a hidden image rise out of the noise as you cross your eyes. CAPTURE DEPTH FIVE WAYS • LiDAR live capture on iPhone Pro and iPad Pro — point, freeze, done • On-device AI depth from any photo (Depth Anything V2) • Scan real objects with Apple's Object Capture (Pro devices) — guided orbits turn a real object into a .usdz you can orbit and frame • 3D model import — .usdz, .usd, .obj, .scn with an orbit camera so you choose the angle • Bundled height map and 3D model presets to play with right away PICK A PATTERN • Six procedural generators: random dot, stars, Perlin noise, Worley noise, Voronoi cells, reaction-diffusion • Import any image from your photo library as a custom tile • Built-in texture library TUNE EVERY KNOB • DPI, depth strength, separation, oversampling • Remap input and output depth ranges to push the subject forward or back • Denoise quantized 8-bit imports for clean, banding-free output • Invert depth in one tap • Live preview redraws as you slide PRIVATE BY DESIGN Everything runs on device. No account, no upload, no tracking, no ads. Your photos and 3D scans never leave your device. UNDER THE HOOD Parallelized implementation of the Thimbleby–Inglis–Witten autostereogram algorithm with W. A. Steer's link-based hidden-surface refinement. Powered by ARKit, Object Capture, Core ML, SceneKit, Metal, and Core Image. Output is upscaled so the minimum dimension is at least 960 px — print-ready or share-ready. SHARE Export high-resolution PNGs to Photos, Messages, AirDrop, or any app with a share sheet. Available in English and French. For iPhone and iPad (iOS 18 or later) and Mac with Apple silicon (macOS 15 or later). LiDAR capture and Object Capture scans are iPhone and iPad only. Capture a scene. Pick a pattern. Stare into it.
