Compress JPEG to 30 KB
Need a JPG under 30 KB? Drop in any photo or screenshot — it is converted to JPEG and compressed to the best quality that fits. Everything runs in your browser — nothing is uploaded. Need different dimensions instead? Resize or convert.
Why compress to 30 KB?
30 KB is a common upload limit for passport-style photos on exam, job and visa application portals. At that size a JPG photo can be about 430×320 pixels at medium quality.
About 430×320 px fits
At medium quality a detailed JPG photo of roughly 430×320 pixels lands under 30 KB; at high quality about 300×220.
Typical use
30 KB limits are common for passport-style photos on exam, job and visa application portals.
119× smaller than a phone photo
A 12 MP phone photo is around 3–4 MB, so it must shrink about 119×. The tool lowers quality first and resizes only if needed.
Quality to expect
At 30 KB, quality is fine for small display. Good for thumbnails, profile photos and forms.
Scans and documents
A scanned A4 page of about 520×730 pixels usually fits, because text pages compress far better than photos.
Exact limit, checked
30 KB is measured as 30,720 bytes (1 KB = 1,024 bytes), the way most upload forms count it, so the file is never just over.

Screenshots and scans at 30 KB
Screenshots are PNG and often 300 KB–2 MB. This page converts them to JPEG first, which alone removes most of the size, then fine-tunes the quality to fit 30 KB.
ID card photos and small scans fit at about 400 pixels wide. Text on an ID stays readable if you crop away the table or desk around it.
Transparency becomes white. JPEG can't store transparent areas, so logos on transparent backgrounds get a white background.
Compare before you upload. Click compare to check the face or text is still clear.

Frequently asked questions
Can a PNG screenshot be compressed to a 30 KB JPEG?
Yes. This page converts it to JPEG and shrinks it until it fits. Crop away empty areas first for the sharpest result.
How many pixels fit in 30 KB?
For a detailed JPG photo, about 430×320 at medium quality or 580×430 at low quality. Simple graphics and scans can be much larger.
What quality will a 30 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 30 KB the same as 30,000 bytes?
Not quite. Most forms count 1 KB as 1,024 bytes, so 30 KB is 30,720 bytes. The tool uses the same count, so a file it marks as under 30 KB is accepted.
Should I use JPG or WebP for 30 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 30 KB?
Very large or detailed images may not reach 30 KB by quality alone. Resize it first (for example to 430 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.
