How many photos fit in 100 KB?

One or two pages of a document photographed with a phone, at a reduced resolution that keeps text readable. For more pages, use the 200 KB page.

What if it cannot fit?

You are told so instead of getting a file the form will refuse: use fewer pages, or crop the photos to the paper first.

Do the photos keep their quality?

They are re-encoded as JPG at the resolution the limit allows — enough for printed text, not for fine photographs.

Is 100 KB counted as 100,000 or 102,400 bytes?

The PDF is kept under 100,000 bytes, so it passes whichever way the form counts a kilobyte, as 1,000 bytes or as 1,024.

My phone photo was sideways. Will the page be too?

No. The orientation the phone records in the photo is applied, so a photo stored sideways comes out upright. With Orientation on Automatic, a landscape photo gets a landscape page.

Are my photos uploaded?

No. The PDF is built in your browser. The free plan takes 3 photos per run, 20 MB each, 5 runs per day.

Example

Example: a mark sheet photographed front and back, in one PDF under 100 KB

An online application form asks for the Class 12 mark sheet as one PDF of at most 100 KB. Both sides are photographed with a phone held upright: 3000 × 4000 pixels each, about 3 MB apiece. The two photos are dropped in order, front first; the page size stays A4 and Keep the PDF under is already 100 KB.

The PDF without photos is measured first: two A4 pages and the footer line, about 1.8 KB. The rest of the 100,000 bytes, less a safety margin, is shared by area: two shares of about 48,400 bytes.
Each photo starts at about 778 × 1,038 pixels. JPEG quality is lowered first, down to 30 %, and only then is the photo made smaller if it is still over its share.
The PDF is saved and weighed. If it is over 100,000 bytes, every share shrinks by the overshoot and the photos are encoded again, up to four times.
If a photo would have to drop below 240 pixels on its long side, its text would be unreadable: no PDF is made, and a message says to use fewer pictures or a larger size.

Photos of 3000 × 4000	Share of each	Starting size
1	≈ 97,400 bytes	≈ 1,104 × 1,471 pixels
2	≈ 48,400 bytes	≈ 778 × 1,038 pixels
3, the free plan’s most per run	≈ 32,100 bytes	≈ 634 × 845 pixels

images.pdf: two A4 pages under 100,000 bytes, each photo centred on its page, sharp enough for printed names and marks. With a single photo the PDF keeps the photo’s name. If small print blurs, crop the photos to the paper first, or use the 200 KB page if the form allows it.

How it works

Photograph the pages flat and well lit, then drop the photos in order.
Keep A4, or choose Same as image; the size limit is already set.
Press Convert to PDF and download a PDF under 100 KB.
