SHRINKSMITHType the KB. Get a sharp photo.
Shrinksmith compresses an image to under an exact size — 20, 50, 200 or 500 KB, or any number you type — and keeps it as sharp as that size allows. The saved file is measured byte by byte, so it really is under the limit a form asks for. Everything happens on your phone, even in airplane mode.
Get it on Google PlayFree with ads: type a size, compress, compare and save as often as you like. Shrinksmith Pro removes ads and unlocks every tool — yearly with a 3-day free trial, monthly, or once for life.
Exactly under your size
Type the limit in KB or MB, or set a range such as 10–20 KB. Shrinksmith checks the real bytes of the saved file and never goes over. 1 KB as 1000 or 1024 bytes — your choice, safe by default.
As sharp as the size allows
Instead of only lowering quality, it tries several pixel sizes and keeps the one that looks best at your size, with an honest sharpness score. Text on documents stays readable.
Before & after slider
Drag the divider to compare the original with the compressed file, pinch to zoom, double-tap for real pixels. The “after” side is decoded from the exact file you will save.
Ready for upload forms
Quick presets for common photo and signature limits, share in from your browser, share the result straight back. Batch many photos to one target.
Your originals untouched
Always saves a new copy in Pictures/Shrinksmith — the original is never edited or deleted. Location and device metadata are removed from the copy by default.
Private & offline
No photo permission: you pick images with the Android Photo Picker. Images are compressed on your phone and never uploaded.
