JPG to PDF 100 KB
Photos fit in a PDF under 100 KB. 100 KB is 102,400 bytes, and it holds 1 phone photo of a page at the default setting and 5 at the smallest. Build the PDF, then compress it to the target.
What 100 KB holds
A phone photo of a page comes down from about 2.7 MB to about 73 KB at the default setting, and to about 18 KB at the smallest. A photo leaves the camera about 27 times larger than 100 KB, and the compress step brings it inside the budget. To convert JPG to a PDF of less than 100 KB, use this free converter: it runs in the tab.
One photo fits at the default setting, at 150 dpi. Up to 5 fit at the smallest setting, which redraws the pages at a lower resolution and keeps typed text readable.
The order to do it in
Assemble first with the images to PDF tool, which writes the original pixels into the page. Then set the target with the 100 KB compress target, which re-encodes the page images and checks the result before it hands it back.
The 100 KB page shows what fits for every kind of document.
Before you take the photo
Fill the frame with the page. Get the light even, so the encoder does not spend bytes on shadow gradients. Hold the camera square, so the page is a rectangle rather than a trapezoid. Crop on the phone.
For more room per page, a 200 KB target doubles the budget. For a tighter cap, a 50 KB target holds a photo at the smallest setting.
Questions people ask
- Can I convert JPG to PDF under 100 KB?
- Yes. One phone photo of a page fits at the default setting, and 5 fit at the smallest setting. Build the PDF first, then compress it to 100 KB.
- Why does cropping the photo help so much?
- Everything in the frame costs bytes. A desk, a hand and a patterned background are detail the encoder has to describe, and they take budget away from the page you need.
- Does the images to PDF step compress my photos?
- No. It writes the original JPG data into the page as it is. The compress step afterwards does the size reduction, which is why the two steps are separate.
- What resolution should I photograph a document at for 100 KB?
- Shoot at whatever the phone gives you and let the compress step decide. It picks the resolution the page needs and keeps the most detail that fits.
