Need to shrink HEIC photos, batch hundreds at once, or work offline on your phone? Image Shrinker does the same job natively — and never uploads anything either.
Why 200 KB is usually enough
A modern 12-megapixel phone photo typically lands between 2 MB and 6 MB straight out of the camera. Re-encoded well, the same photo is often 200–400 KB with no difference you can see at normal viewing size — the original was storing far more precision than the eye resolves.
So a 200 KB target is usually a mild trim rather than a visible loss. The tool takes the highest quality that fits, which for most photos means you keep full resolution and never touch the dimensions.
Where this target fits
- Marketplaces and listings — most cap images between 200 KB and 5 MB.
- Portfolio and application uploads — 200 KB clears nearly every form.
- Email and messaging — send a gallery without hitting attachment limits.
- Web and print-at-home — plenty of resolution for a sharp A4 print.
When not to compress
If you are archiving originals or printing large, keep the untouched file. Compression is for delivery: the copy you send, upload or publish. Keep one original and shrink the copies.
Re-encoding also drops EXIF, which means GPS location, capture time and camera serial number are gone from the output — worth knowing before you post a photo taken at home.
Questions
Are my photos uploaded anywhere?
No. There is no backend. The page contains all the code it needs, and your browser does the decoding and encoding locally. Disconnect from the internet after the page loads and it keeps working — that is the easiest way to verify it.
How do I get a photo under 100 KB for a form upload?
Select the 100 KB preset, drop the file in, and download the result. Most government, visa and job-portal forms accept a JPEG under 100 KB — if the form also caps dimensions, set max dimension to 800 px or 1280 px as well.
Why is the output JPEG when I uploaded a PNG?
PNG is lossless, so a photograph stays enormous unless you crop it. Choosing JPEG or WebP lets the tool actually hit your target size. Switch the output to PNG if you need lossless output and transparency — the tool will then reduce dimensions instead of quality, and may report that the target cannot be reached.
Does it work with HEIC photos from an iPhone?
Usually no — most browsers cannot decode HEIC. Export to JPEG first (iOS: Share → Save to Files → keep as JPEG, or change Camera → Formats → Most Compatible), or use the Image Shrinker app, which handles HEIC directly on-device.
Is there a limit on how many images I can compress?
No limit, and no daily cap. There is no server doing the work, so there is nothing to meter. The mobile app has a free daily batch limit plus a one-time Pro upgrade that removes ads.
What about really large images?
Images are capped at 4096 px on the long edge before processing so a 50-megapixel file does not exhaust browser memory. For a target size like 100 KB that ceiling makes no practical difference.
