This page opens Pocketsize with the size limit already set to 200 KB. Add a picture and the engine saves it several ways — JPEG, PNG, WebP and AVIF — measures every attempt against your original, and keeps the smallest version that fits under the limit and still looks right.
A 200 KB cap usually comes from a form or an upload field that refuses anything bigger. Most tools hit the number by shrinking the pixels and hoping. Pocketsize works to the byte budget directly: it searches quality levels for the best-looking file that fits, shows you the visual-match score it measured, and says so plainly if the only way under the cap would wreck the picture.
Your pictures never leave your computer: the compression runs in your browser, on your own device, and you can verify that yourself in about a minute. After one visit it even works with no internet at all.
This page is Pocketsize with the plan pre-set for one job. Nothing is locked — change any control once it is open.
Pocketsize keeps the smallest version that is still worth looking at and tells you the limit was missed, instead of handing you a ruined picture that technically fits.
Only if the plan allows shrinking — and whenever pixels were removed, the same line that shows your saving says so. Set “Shrink big photos” to “never” and the pixel count is untouched.
No. The compression runs in your browser, and the page's own security policy makes a network upload impossible — there are instructions for checking that yourself, in the link above.
