How to
How to convert JPG to PDF under 300 KB
- 1.
Add your pages. Photos or scans of each page, or a PDF you already have, in the order they should appear. About 3 to 5 scanned A4 pages stay readable under 300 KB.
- 2.
Keep the 300 KB limit. It is already set. The tool builds the PDF, or compresses yours, until it is under 300 KB: about 150 KB a page for two pages, 60 KB for five.
- 3.
Download the PDF. Check the size shown, then upload it to your form.
Why this size
Why forms ask for a PDF under 300 KB
300 KB is the usual limit when a form wants several certificates in one PDF. It fits 3 to 5 scanned pages, each with about 60 to 100 KB, which keeps stamps, signatures and small print legible.
Add the documents in the order the form lists them; the PDF keeps that order. To reduce a PDF size to 300 KB that you already have, add it on its own. For more pages, under 500 KB leaves more room for each.
| Size limit | Readable A4 pages |
|---|---|
| Under 200 KB | 2 to 4 |
| Under 300 KB (this page) | 3 to 5 |
| Under 400 KB | 4 to 6 |

FAQ
JPG to PDF under 300 KB: questions
- Can I put several certificates in one PDF under 300 KB?
- Yes. Add them in the order the form wants; each becomes a page, and the whole PDF is compressed under 300 KB.
- How do I reduce PDF size to 300 KB?
- Add the PDF and keep the 300 KB limit. The photos inside are compressed first, so typed text stays sharp and selectable.
- Will a 300 KB PDF print clearly?
- Typed and scanned text prints clearly. Photos inside look softer up close, but stay recognisable.
- How do I convert JPG to PDF under 300 KB?
- Add your photos, keep the 300 KB limit and download. The PDF is built and compressed on your device until it fits.
- How many pages fit in 300 KB?
- About 3 to 5 A4 pages of scanned text stay comfortably readable. Photos with lots of detail need more space per page.
- How do I compress a PDF to 300 KB?
- Add the PDF here instead of photos and keep the 300 KB limit: the tool reduces the PDF size until it is under 300 KB. The photos inside are compressed first, so typed text stays text; only if that is not enough are the pages saved as images.
- What if the PDF cannot get under 300 KB?
- You will see the size it reached. Crop the photos to the page, add fewer pages, or use a larger limit if your form allows it.
- Are my documents uploaded?
- No. The PDF under 300 KB is built in your browser, so certificates, IDs and other private documents never leave your device.

How the tool works
Each image becomes one page of a PDF built in your browser, and a PDF you add keeps all its pages, in the order you add the files. With a size limit, the tool first compresses the photos inside the PDF, quality first and size second, while typed text, links and drawings stay as they are, so the text can still be selected. Only if that is not enough is each page drawn with pdf.js (Mozilla, Apache 2.0) and saved as an image, smaller pages before lower quality, until the whole file is under the limit. Nothing is uploaded. Everything happens in your browser; your images are never uploaded.
