JPG to PDF under 200 KB

To make a PDF under 200 KB, PixelFit compresses the JPG to at most 199,262 bytes and wraps it in a one-page PDF with about 738 bytes of PDF structure, 200,000 bytes or less in total. Measured: an A4 scan at 150 DPI fits at quality 61; a 4:3 photo at about 1,013 × 759 pixels (quality 75).

PDF · under 200 KB (at most 200,000 bytes) · original pixel size · white background

PixelFit aims at 200,000 bytes or less, so the file passes whether the form counts 1 KB as 1,000 or 1,024 bytes.

Saving presets is part of Pro.

Where the 200 KB go in a JPG-to-PDF file

Of the 200,000 bytes that pass as 200 KB under both KB definitions, PDF structure takes 738 bytes for one A4 page (computed with PixelFit's own writer), leaving 199,262 bytes, 99.6 %, for the JPEG; ten pages leave 19,475 bytes each.

For one photo, quality 75 allows 1,013 × 759 pixels and quality 90 797 × 597; a full 12 MP frame must be scaled down first, which the tool does for you.

How many pages fit in a 200 KB PDF

The 200,000 bytes of 200 KB, less 738 bytes of PDF structure for the first page and about 501 for each extra one, shared evenly.

A4 and Letter pixel sizes against 200 KB

Readable pages and photos in 200 KB

At 200 KB, 1 typed A4 page at 150 DPI fits at quality 50 or better (none at 200 DPI), but not one photo of 1600 × 1200 at quality 70.

One page alone gets quality 61 at 150 DPI and quality 33 at 200 DPI; at 300 DPI even quality 30 is 1.7 times too big.

One image free, several merged with Pro

Free: each image becomes its own one-page PDF under 200 KB. Pro: several images merged into one PDF under 200 KB, on your device; 5 pages get 39,452 bytes of JPEG each.
