How to make a PDF under 100 KB

  1. Add your images

    Photos, scans or screenshots, in JPG, PNG or WebP. Several at once is fine.

  2. Put them in order

    Drag the thumbnails or use the arrows. Turn any page that lies on its side.

  3. Keep the limit at 100 KB

    It is already set. Change it if your form allows more or less.

  4. Create and download

    The size shows next to the download button, already under the limit.

What fits in 100 KB

One A4 page fits comfortably. In our tests, a phone photo of a printed page kept about 1,400 pixels on its long side, around 130 DPI on the page, and the print was sharp. Two pages kept about 920 pixels each, around 80 DPI, still easy to read. Three pages dropped to about 65 DPI, where ordinary 10 point print is readable but soft.

That makes 100 KB a good fit for one or two pages: a certificate, ID card, mark sheet or letter. For longer documents, check whether the form takes a bigger file, or use our under 200 KB page.

How the tool stays under the limit

Each page is measured first, so a busy photo gets more of the space than a plain page of text. Then every page is saved at the highest quality its share allows, and made smaller only when quality alone cannot get there, because a slightly smaller page at good quality reads better than a large one full of blocks.

Websites count a kilobyte as 1,000 or 1,024 bytes, so the tool keeps the PDF under the limit counted the smaller way. A PDF it makes under 100 KB passes a 200 KB limit either way.

Tips for a sharper PDF

Photograph documents flat, straight on and in good light, and crop away the table around them. Leave out pages the form does not ask for. If a form wants each document as its own file, tick One PDF per image: every PDF then stays under the limit on its own.

Questions

How do I convert JPG to PDF under 100 KB?

Add your images, keep the limit at 100 KB and choose Create PDF. The PDF you download is already under the limit.

Will the text still be readable?

Yes for one or two A4 pages. In our tests, ordinary 10 point print stayed easy to read on two pages, and was readable but soft on three.

What if the PDF is still over the limit?

With many pages and a small limit, each page gets only a few kilobytes. The tool shrinks the pages until they fit, and tells you if a PDF stays over even at the lowest useful quality. Remove pages, or split them over two PDFs if the form allows.

Are my documents uploaded?

No. Your browser makes the PDF on your device, so the images are never sent to uncrop.si or anyone else. Once the page has loaded, it even works offline.

Can I set a different limit?

Yes. Pick another preset, or type any size in KB or MB.

Does it work on a phone?

Yes. Open this page in your phone browser, choose the photos from your gallery, and the PDF is saved to your downloads.
