Exam and government portals often want a JPG under 20, 50 or 100 KB, but your certificate or ID proof is a PDF. This tool turns each page into a JPG and searches for the best quality that fits under your limit, lowering the JPEG quality first and the resolution only if it has to. It shows the final size and pixel dimensions of every page. Everything runs in your browser.
How to use it
- Choose your PDF or drop it here.
- Pick the size the portal asks for: 20, 50, 100, 200 or 500 KB, or type your own.
- Press Convert and wait while each page is fitted.
- Check each page's size and dimensions in the list.
- Download one page, or all of them as a ZIP.
Frequently asked questions
Is my PDF uploaded anywhere?
No. Pages are rendered with pdf.js and encoded as JPG in your browser. Certificates, ID proofs and mark sheets stay on your device.
How does it get each page under the limit?
It first lowers the JPEG quality, step by step, keeping the full resolution. Only if that is not enough does it reduce the pixel size, then raises the quality back up as far as the limit allows. You get the sharpest image that still fits.
The portal says 50 KB. Will a 49 KB file pass?
Yes. The tool aims under the limit counted as 1,000 bytes per KB, which is the stricter reading, so the file passes whether the portal counts a kilobyte as 1,000 or 1,024 bytes.
Will the text still be readable at 20 KB?
For a single printed page, usually yes, but it is at the edge. At 20 KB an A4 page ends up around 70 to 100 DPI with visible JPEG blocks. Open the result and zoom in before you upload. Faint stamps and small handwriting suffer first.
Some pages stayed over the limit. What now?
A page full of photos or dense colour can be too big even at 50 DPI and low quality. Try a lower starting resolution, crop the page first, or check whether the portal accepts a slightly bigger file. The smallest version is still offered so you can see how close it got.
