Type the size a form asks for — 50 KB, 100 KB, 200 KB — and get a picture at or under it. The tool finds the highest quality that fits, shrinking the pixels only when it has to. Nothing is uploaded: the work happens inside your browser, on your own device.

- Set the target size Type it in KB, or tap one of the quick sizes. The presets fill in what common exam and government forms ask for.

Questions
- How do I compress an image to 50 KB?
- Drop the image, type 50 in the target box and press Compress. The tool tries JPEG qualities from high to low and, if the picture is still too large at the lowest sensible quality, scales it down a little and tries again until it fits under 50 KB.
- Will it look bad?
- Rarely. Photographs compress remarkably well — a phone picture of several megabytes is usually fine at 100 KB. Very small targets like 20 KB force a smaller picture, which is what those forms expect anyway.
- Does it work for PNG?
- Yes. PNG is lossless, so the only way to make one smaller is to reduce its pixels; choose PNG as the output if you must keep it as PNG, or leave the output on Auto to get a much smaller JPG or WebP.
- What sizes do Indian exam forms want?
- They vary, so check your form. Common requirements are a JPG photo of 20–50 KB at roughly 3.5×4.5 cm and a signature of 10–20 KB. The presets on this page match those, and the passport photo tool crops to the exact shape.
- Is the image uploaded anywhere?
- No. Compression runs in your browser using your device. Nothing is sent, stored or seen by anyone.
