About this free bulk image resizer

Government portals, exam forms and job applications across India and Pakistan reject photos over strict KB limits — and doing them one by one is painful when you have ten documents. This bulk image resizer fixes that: upload unlimited JPG, PNG or WebP photos, set one target size, and every image is tuned to fit it. The engine binary-searches the JPEG quality setting for each photo (shrinking dimensions only as a last resort) until the output lands at or just under your target, so text on documents and ID cards stays crisp. Unlike competitors that cap free batch conversions, here bulk is unlimited and free forever. Everything is computed locally with the Canvas API: no server, no queue, no account, no watermark. It works offline once the page is loaded and never stores or transmits your photos.

Frequently asked questions

How do I resize multiple images to 20KB at once?

Drop all your photos in, select the 20KB preset and click Resize All. Each image is resized to 20KB or slightly under, then download them one by one or all together.

How many images can I resize in one batch?

Unlimited. Files never leave your device, so there is no upload cap — very large batches just take a little longer to process.

Can I mix JPG and PNG photos?

Yes. JPG, PNG and WebP are all accepted in the same batch; output is JPEG (best for photos).

Is my photo quality preserved?

Quality drops only as far as needed to hit your KB target. For ID photos, signatures and documents the result stays sharp and readable.
