Compress JPEG to 50 KB
"Photo in JPG format, maximum 50 KB" is one of the most common upload rules. This page meets both parts: JPEG output, under 50 KB. Everything runs in your browser — nothing is uploaded. Need different dimensions instead? Resize or convert.
Why compress to 50 KB?
Many sites cap images at 50 KB — typically for passport-style photos on exam, job and visa application portals. That leaves room for roughly a 550×410 JPG photo.
About 550×410 px fits
At medium quality a detailed JPG photo of roughly 550×410 pixels lands under 50 KB; at high quality about 380×290.
Typical use
50 KB limits are common for passport-style photos on exam, job and visa application portals.
72× smaller than a phone photo
A 12 MP phone photo is around 3–4 MB, so it must shrink about 72×. The tool lowers quality first and resizes only if needed.
Quality to expect
At 50 KB, quality is fine for small display. Good for thumbnails, profile photos and forms.
Scans and documents
A scanned A4 page of about 670×950 pixels usually fits, because text pages compress far better than photos.
Exact limit, checked
50 KB is measured as 51,200 bytes (1 KB = 1,024 bytes), the way most upload forms count it, so the file is never just over.

Meeting a 'JPG, max 50 KB' photo rule
Format and size together. Uploading a PNG renamed to .jpg can fail the format check; a large JPG fails the size check. This page re-encodes as a real JPEG and compresses it to fit.
What 50 KB holds: a portrait around 520 pixels wide at good quality — more than enough for any form.
iPhone photos (HEIC) should be converted first with HEIC to JPG, then compressed here.
Safer margin: if a portal is strict, use 45 KB.
Keep the original format: resize image to 50 KB.

Frequently asked questions
How do I make a JPG photo under 50 KB?
Drop it here and click Compress. The tool finds the best JPEG quality under 50 KB and reduces the dimensions if needed.
How many pixels fit in 50 KB?
For a detailed JPG photo, about 550×410 at medium quality or 750×560 at low quality. Simple graphics and scans can be much larger.
What quality will a 50 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 50 KB the same as 50,000 bytes?
Not quite. Most forms count 1 KB as 1,024 bytes, so 50 KB is 51,200 bytes. The tool uses the same count, so a file it marks as under 50 KB is accepted.
Should I use JPG or WebP for 50 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 50 KB?
Very large or detailed images may not reach 50 KB by quality alone. Resize it first (for example to 550 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.
