How do I compress an image to 100KB?

Choose the image, pick 100KB as the target (or type any number), and download. The compressor searches for the best quality that fits under your limit, scaling the image down only when quality alone cannot get there.

What if my image can't reach the target size?

You are told plainly, and given the smallest file that was achievable. A tool that silently returns an over-budget file wastes your time at the upload form — honesty here is the feature.

Does compressing reduce the quality?

Some, by definition — that is where the bytes go. The search always uses the highest quality that still fits your target, and at typical targets the difference is hard to see at normal viewing size.

What formats can I compress?

JPG, PNG, WebP, HEIC, AVIF, GIF, BMP and TIFF all work as input. Lossy formats stay in their format; lossless ones are re-encoded as JPEG, because a byte target needs a format with a quality dial.

Why can't I set a size target for PNG output?

PNG is lossless — it has no quality dial to search over, so no honest way to hit an arbitrary byte count. Compressing to a target converts to JPEG instead, which is what the forms demanding 'under 100KB' expect anyway.

Is my photo's location data removed?

Yes, by default. Phone photos carry the GPS coordinates of where they were taken; compressing a file for upload is not consent to publish that. Tick 'keep metadata' if you genuinely want it preserved.

Compress Image

Shrink a photo to an exact file size — 100KB, 50KB, whatever the form demands — or just pick a quality. If the target is impossible, you are told, not fooled.

How to compress an image to an exact size

1
Choose the image — JPG, PNG, WebP, HEIC and more all work.
2
Pick the size you need: 50KB, 100KB, 200KB, or type your own.
3
Select Compress image — the best quality under that size is found automatically.
4
Check the before and after sizes, then download.

Why "compress to 100KB" is the real job

Most compressors offer a quality slider and leave the arithmetic to you: move it, download, check the size, move it again. But nobody wakes up wanting quality 63 — they have a visa portal, a job application or a marketplace form that rejects anything over a stated limit. This tool takes the limit directly and runs that loop itself, searching qualities (and, when quality alone cannot get there, scaling the image down) until the file fits.

And when it genuinely cannot fit — a huge panorama into 10KB — it says so and hands you the smallest it achieved, because an upload form will measure the file itself and no confident-sounding download changes that.

Smaller file, safer file

Phone photos carry metadata: the camera model, the settings, and usually the GPS coordinates of where the picture was taken. Compressing a photo to upload it somewhere is not consent to publish your location, so that data is stripped by default — which also saves a few kilobytes toward your target.

Need a different format rather than a smaller file? Use the image converter. Working with documents instead? The PDF compressor does the same honest job for PDFs.

About Image Compressor

Forms, portals and upload fields love exact limits — a passport application wants under 100KB, a job portal under 200KB, a marketplace under 1MB. This compressor works the way those limits do: tell it the size you need and it searches for the best quality that fits under it, re-encoding and, when necessary, scaling until the file complies. Or skip the target and just pick a quality. Either way you see the original size, the new size, and the quality that was used — and if your target is genuinely impossible for that image, the tool says so and gives you the smallest it could make, rather than quietly handing back a file that will be rejected.
