SnapSize: Compress Photo to KB

Need a smaller photo for a form, an email or an application? SnapSize is a photo compressor and image resizer that reduces image size from MB to KB right on your phone. Set the exact size, pick your photos, and you are done. Processing happens on your device, so your photos are never uploaded.

📏 COMPRESS PHOTOS TO AN EXACT SIZE
Tap 50 KB, 100 KB, 200 KB, 500 KB or 1 MB, or type the limit you need. SnapSize lowers quality first and reduces resolution only if needed, to keep the picture sharp. If a size cannot be reached, the app tells you instead of quietly going over it.
Prefer a simple choice? Shrink by quality instead: smallest file, balanced or high quality.

👀 KNOW THE SIZE BEFORE YOU START
See how big your images are now and about how small they will get. Preview one photo first, then compare before and after with a slider.

📐 RESIZE IMAGES AND CROP PHOTOS
• Resize images to an exact width and height in pixels, or by percentage
• Lock the aspect ratio to keep the proportions
• Crop by hand or with 1:1, 4:3, 3:4, 16:9, 3:2 and 35×45 mm

🖼️ READY SIZES FOR YOUR UPLOADS
Instagram square and portrait, Story, Facebook post, YouTube thumbnail, passport 35×45 mm and photo 50×60 mm. These are sizes only, so always check the rules of the place you apply to.

🔄 CONVERT IMAGE FORMATS
• Convert between JPG, PNG and WEBP
• Open iPhone HEIC photos and convert HEIC to JPG (Android 9 and newer)

📦 BATCH COMPRESS PHOTOS AND WHOLE FOLDERS
Select several images, pick a whole folder, or share photos to SnapSize from your gallery. Photos keep their order, and you can stop at any time without losing the finished ones.

♻️ REPLACE ORIGINALS, WITH UNDO
Results are saved as copies and your originals stay as they are. To free up storage, you can choose to put the smaller photo in the original's place, and undo it on the result screen.

🗂️ TIDY FILES
• Saved to Pictures/SnapSize, with an "Open photo" button
• Clear file names: the original name when Android shares it, otherwise the capture date
• Keep or remove the capture date and camera info
• GPS location is removed from every result
• Compress never saves a copy larger than the original

🔒 PRIVATE AND OFFLINE
All processing happens on your device, and compressing works without internet. Only ads and purchases need a connection.

📋 HISTORY, WIDGET AND SHORTCUTS
Every result is saved in History, with filters and bulk delete. A home screen widget shows today's savings, and long-pressing the app icon opens each tool.
