Compress image

Bring a photo under a size limit in KB — the exact one an application form states and refuses to bend on, whether that is 20 KB for a passport photo, 50 KB for a signature, or a few hundred KB for a scanned certificate. Everything runs in your browser, so the photo is never uploaded, there is no sign-up, and nothing is watermarked.

KB

The tool gets as close to this as it can without going over.

This tool runs in your browser, not on our server. Your file is never uploaded, and it is gone when you close the page.

Give it the number the form asks for and it works out the rest. It lowers the JPEG quality first and only reduces the dimensions when the limit cannot be met by quality alone, so you keep as much of the picture as the size allows rather than overshooting and handing back a photo blurrier than it needs to be. The result shows the new size beside the original before you download anything, and says plainly when it had to resize the photo to fit.

A 12-megapixel phone photo is worked on at up to 3000 pixels on its long edge — more than enough detail for any photo an upload form checks, and far quicker on a budget phone than searching at full resolution. If the number the form gives is a pixel size like 200 × 230 rather than a size in KB, use Resize image instead; if you have several photos to turn into one document, compress each here and then combine them with Image to PDF.

How to compress an image

  1. Open your photo. Drag it onto the drop zone, or tap to browse. It is read on your device — nothing is uploaded.

  2. Set the target size. Tap one of the common limits — 20, 50, 100, 200 or 500 KB — or type the exact number the form gives you.

  3. Compress and download. The result shows the new size beside the original, and says if it had to resize the photo to get there. A long search can be stopped at any point.

Frequently asked questions

How do I get a photo under 50 KB?

Pick the 50 KB preset and press Compress image. The tool lowers the JPEG quality first and only then reduces the dimensions, so you keep as much of the picture as the limit allows. Most phone photos reach 20 KB or 50 KB without becoming unreadable.

How do I compress a photo to 20 KB for an application form?

Tap the 20 KB preset and press Compress image. A tight budget like this usually needs the photo made smaller in pixels as well as lower in quality, so the tool does both and tells you the final dimensions. A head-and-shoulders passport photo still reads clearly at 20 KB; a busy full-length photo may not, in which case crop to the face first.

The form wants my photo between 20 KB and 50 KB. What do I set?

Set the target to the top of the range — 50 KB. The tool gets as close under that as it can without going over, so the result lands inside the band the form allows. If it comes back well under 20 KB, your original was already small; that is still accepted, since 20 KB is a floor the portal sets to reject blank uploads, not a size it insists you hit.

Why is my photo smaller in pixels than it was?

Because the limit could not be met by quality alone. A very tight budget needs fewer pixels as well as lower quality, so the tool resizes and tells you the new dimensions. If your form also states a minimum width, check that number against what the result shows and crop rather than shrink if you are close to it.

Does compressing reduce the quality of the photo?

Yes — that is how the file gets smaller. JPEG compression drops detail the eye is least likely to miss, and the tool uses only as much of it as your target requires. For a photo headed to an upload form this is the right trade: the portal is checking that a face is visible, not judging the image. If you need the dimensions changed without losing quality, that is Resize image.

Why is the result always a JPG?

Because a size budget cannot be met with a PNG — it is lossless, so there is no quality to trade away — and some government portals still refuse WebP. JPG is the format that both compresses and gets accepted. If you uploaded a PNG signature, the transparent background becomes white in the JPG, which is what a document expects anyway.

My photo is already under the limit. Why will it not compress?

The tool stops and tells you the current size when your photo is already smaller than the target, because compressing it further would only lose quality for no reason. Upload it as it is. If you meant to hit a lower number, type that in the box.

Is the photo uploaded to compress it?

No. It is read and re-encoded by your own browser, and it never leaves your device. There is no server to receive it and nothing is stored — closing the page is enough. That matters with a photo or signature you are about to attach to a government application.
