Reduce image file size to exactly 25KB
25KB is the range most government and exam forms ask for. The tool re-encodes on a canvas and steps quality down until the file fits, reducing dimensions only if it must — a head-and-shoulders portrait typically settles near 440x330 pixels and still looks clean. Processing is local; nothing leaves the browser.
A browser-based compressor that re-encodes an image until it falls under 25KB, a budget that holds roughly 440x330 pixels of photographic detail.

Form photographs are small and face-centred, which compresses well. At 25KB you have room for about 440x330 pixels — more than most portals display.
Skin and hair compress efficiently. What degrades first is fine background texture, which no form checker looks at.
Crop and resize to the required pixel size before compressing, otherwise the tool spends the byte budget on pixels the form will discard.
Compression runs on your own device using the Canvas API. There is no upload step and no server involved.
Compress Image to 25KB serves the range most exam and government portals specify. It is tight enough to need care and generous enough that a portrait survives it well, usually at about 440x330 pixels.
The image is decoded, drawn to an offscreen canvas and re-encoded. Quality is stepped down and measured against the 25KB ceiling on each pass; dimensions are reduced as well, because quality alone cannot reach this target on photographic content.
Application and examination forms, which commonly cap photographs near 25KB. Always take the exact figure from the official notification — portals differ and change between cycles.
Reaching 25KB means discarding roughly 164x the data in a typical 4MB phone photograph, and nothing restores it. At this budget text within an image becomes hard to read and fine texture disappears; compress from the highest-quality original you have, never from an already-compressed copy.
The image is decoded and re-encoded by your own browser using the Canvas API. There is no upload endpoint, so the file cannot reach a server; closing the tab discards everything.
