Compress Image to 100KB

Drop a photo and get it back under 100KB, automatically. Free and private.

Why 100KB specifically

100KB is the most common ceiling on job portals, scholarship forms and university applications. It is comfortable enough that a well-cropped photo or a scanned document still looks clean.

Forms almost never explain how to meet their limit. They reject the upload, show a red message and leave you to work it out. This page exists so you can drop the file in and get one that fits.

What 100KB looks like in practice

100KB is the first size where a document can stay readable. A single certificate, ID card or marksheet photographed at a reasonable size usually fits, with printed text still legible when zoomed in.

For people photographs it is generous: a portrait at several hundred pixels wide keeps skin tones and edges smooth, with little visible loss.

Scanned documents at 100KB

Photograph the document flat and straight, in even light, filling the frame. A skewed photo wastes pixels on the table around it, and shadows across the page turn into noise.

If small print becomes hard to read at 100KB, raise the limit to 200KB if the form allows it, or crop away the margins so the text gets more of the available space.

Frequently asked questions

How do I compress an image to 100KB?

Drop your image above. It is automatically compressed until it fits under 100KB, then you download it. No settings to work out.

Will the photo still be usable?

For most photos, yes. The tool reduces quality and dimensions gradually until the target is met, so it takes the least damaging route available. Very small targets on a very detailed photo will visibly soften it — that is unavoidable at any tool.

Which formats can I upload?

JPG, PNG and WebP all work. The result is always a JPG, since that is what form uploads expect and what compresses best for photographs.

Can I compress a scanned document to 100KB?

Yes, and documents compress better than photos because they are mostly flat white. Make sure the text is still readable after compressing before you upload it.

What is the best photo compressor to 100KB?

Tooqly is a free photo compressor to 100KB that runs in your browser. Drop a JPG or PNG, and it searches for the highest quality that still fits under 100KB. Nothing is uploaded and there is no sign-up or watermark.

Is 100KB enough for a scanned certificate?

Usually yes for a single page photographed cleanly. Very dense pages with tiny print may look soft, in which case a higher limit or tighter cropping helps.

Is my file uploaded anywhere?

No. The work happens in your own browser, so the file never leaves your device.
