Compress JPEG to 90 KB
For forms that say 'JPG only, maximum 100 KB'. This page always saves JPEG and targets 90 KB, so the file type is right and the size is safely under the limit. Everything runs in your browser — nothing is uploaded. Need different dimensions instead? Resize or convert.
Why compress to 90 KB?
90 KB is a common upload limit for profile photos and document uploads with a strict limit. At that size a JPG photo can be about 740×560 pixels at medium quality.
About 740×560 px fits
At medium quality a detailed JPG photo of roughly 740×560 pixels lands under 90 KB; at high quality about 520×390.
Typical use
90 KB limits are common for profile photos and document uploads with a strict limit.
40× smaller than a phone photo
A 12 MP phone photo is around 3–4 MB, so it must shrink about 40×. The tool lowers quality first and resizes only if needed.
Quality to expect
At 90 KB, quality is fine for small display. Good for thumbnails, profile photos and forms.
Scans and documents
A scanned A4 page of about 900×1270 pixels usually fits, because text pages compress far better than photos.
Exact limit, checked
90 KB is measured as 92,160 bytes (1 KB = 1,024 bytes), the way most upload forms count it, so the file is never just over.

Compress an image to 90 KB in 3 steps

- The target is already set to 90 KB. Leave “Remove EXIF metadata” ticked to save extra bytes.
- Click Compress and download a JPG under 90 KB.

Passing a strict 'JPG under 100 KB' rule
Two rules trip people up: the format (a PNG renamed to .jpg is still a PNG and can be rejected) and the size (100 KB counted as 100,000 bytes). This page solves both — it re-encodes every image as a real JPEG and aims for 90 KB.
Transparent PNGs get a white background, since JPEG cannot store transparency.
Photos for applications look sharp at about 500 pixels wide within 90 KB. Reduce the width on the Resize tab if the quality drops too far.
Keep your original format instead: resize image to 90 KB. Other JPEG targets: 300 KB, 500 KB.

Frequently asked questions
Does renaming a PNG to .jpg make it a JPEG?
No — the file inside is still PNG, and some systems detect that. This page truly converts it to JPEG.
How many pixels fit in 90 KB?
For a detailed JPG photo, about 740×560 at medium quality or 1010×750 at low quality. Simple graphics and scans can be much larger.
What quality will a 90 KB photo have?
Fine for small display. Good for thumbnails, profile photos and forms. The tool keeps the dimensions where it can and lowers compression quality first, so faces and text stay readable.
Is 90 KB the same as 90,000 bytes?
Not quite. Most forms count 1 KB as 1,024 bytes, so 90 KB is 92,160 bytes. The tool uses the same count, so a file it marks as under 90 KB is accepted.
Should I use JPG or WebP for 90 KB?
JPG is accepted everywhere and is the safe choice for forms. WebP holds about 30% more detail at the same size, ideal for websites that support it.
Why is my file still over 90 KB?
Very large or detailed images may not reach 90 KB by quality alone. Resize it first (for example to 740 pixels wide) with the resizer, then compress again.
Are my images uploaded anywhere?
No. They are read and compressed by your own browser and never leave your device. You can disconnect from the internet once the page has loaded and it will still work.
