SnapShrink
Image compressor for Android and iOS
Make photos lighter,
not worse.
Shrink pictures by up to 90% right on your phone. No uploads, no account, no watermarks — and you see exactly what you saved before you keep it.
What it does
Everything you need, nothing you don't.
A compressor should be fast, honest about what it changed, and incapable of leaking your photos. That is the whole brief.
Nothing leaves your phone
No uploads, no account, no cloud queue. Your photos are read, resized and written back on the device, which is why it works with the data switched off.
Up to 90% smaller
A 4 MB camera photo routinely lands in the few-hundred-kilobyte range at the default settings, and still looks right at full screen.
You set the trade-off
One slider for quality, one for the longest side. Leave the defaults alone for a sensible result, or push them until the size is exactly what you need.
Crop, rotate, flip
A built-in editor with free and fixed ratios, straight edges and instant rotation. Crop first, compress second, in a single pass.
Whole albums at once
Select a batch, choose the settings once, and watch the saving for every file. Crop the ones that need it and skip the rest.
JPG, PNG and WebP
Convert as you compress. WebP for the smallest file, JPG for sharing anywhere, PNG when you need it lossless.
Never bigger than before
If your settings would produce a larger file, SnapShrink keeps your original and says so. You cannot accidentally inflate a photo.
See it before you keep it
Every result opens on a compare view with the original beside it and both file sizes in plain numbers. Save it or throw it away.
How it works
Three taps from heavy to light.
Pick your photos
One image or a whole batch, straight from your system photo picker or the camera. SnapShrink only ever sees what you hand it.
Set quality and size
Nudge the quality slider, cap the longest side, choose an output format. Crop and rotate here too, if the shot needs it.
Compare, then save
See the original beside the result with both file sizes. Keep it to your gallery, share it straight out, or discard and try again.
Why it's worth it
Smaller photos solve a surprising number of problems.
Get your storage back
Camera photos are the biggest thing on most phones. Running a few hundred through SnapShrink frees gigabytes without deleting a single memory.
Send without the wait
Email attachment caps, upload forms stuck at 2 MB, a bad signal at the airport. A smaller file goes through first time.
Faster sites and listings
Product shots, marketplace listings and blog images load quicker — and rank better — when they are not full-resolution originals.
Share a copy, not the source
Re-encoding drops the metadata that rode along with the photo, GPS coordinates included, so what you post is a copy rather than your camera roll original.
FAQ
Questions people actually ask.
Are my photos uploaded to a server?
No. Every step — reading the file, resizing, re-encoding, writing the result — happens on your own device using the operating system’s own image libraries. SnapShrink has no account system and no photo storage, so there is nothing for us to upload a photo to. It also means compression keeps working on a plane or in a dead zone.
How much smaller will my photos get?
For a typical 12-megapixel phone photo, 70–90% smaller is normal at the default settings, and the result usually still looks the same on a screen.
The exact saving depends on the picture. A detailed photo of leaves or gravel holds more information than a flat screenshot, so it compresses less. SnapShrink shows you the before and after size for every image, and you can tune quality and dimensions until you like the trade-off.
Does compressing ruin the quality?
JPEG and WebP compression is lossy, so some information is discarded by design. The point of the defaults is to discard the part your eye does not notice. You can compare the original and the result side by side before you save anything, and if a setting goes too far, pull the quality slider back up and run it again.
Can it make a photo bigger than the original?
It will not save a result that is larger than what you started with. If your chosen settings would produce a bigger file — which happens with images that are already heavily compressed — SnapShrink keeps the original instead and tells you it did.
Which formats are supported?
JPG/JPEG, PNG and WebP, and you can convert between them. WebP usually gives the smallest file at a given quality, JPG is the safest choice for sharing anywhere, and PNG is the one to keep when you need a lossless image or transparency.
Can I compress many photos at once?
Yes. Pick a batch, set the quality and size once, and SnapShrink works through the whole set, showing the saving for each one. You can crop each photo on the way through, or skip the ones that do not need it.
Does it strip location data from my photos?
Re-encoding an image drops the metadata that came with it, including GPS coordinates, camera model and timestamps, so a compressed copy is generally safer to share publicly than the original. Orientation is preserved, so your photos will not come out sideways. Treat this as a useful side effect rather than a guarantee: if scrubbing metadata is critical for you, verify the output with a tool built for that.
Is it free? Are there watermarks?
SnapShrink is free and supported by ads. There are no watermarks on your images, no export limits, no subscription and no sign-up.
Do I have to give it access to all my photos?
No. Choosing images goes through your system photo picker, which hands SnapShrink only the files you select and nothing else. The app asks for the camera only if you choose to take a new photo, and for permission to write to your library only when you save a result.
Is there an iPhone version?
Yes. SnapShrink is on both Google Play and the App Store, and the two are built from the same codebase, so they do the same things in the same way.
Free, no account
Shrink your first photo in ten seconds.
