JPG to PDF Under 100KB
Build a multi-page PDF from your photos, automatically compressed to fit.
Drag & drop up to 10 photos, or click to browse
JPEG, PNG, or WebP
Plenty of application forms and upload portals ask for a PDF specifically, but cap it at a strict size like 100KB — a limit that a single normal-quality photo can blow past on its own, let alone several bundled together. This tool builds a PDF from your images the same way our full-quality converter does, then automatically re-compresses each embedded photo and rebuilds the file as many times as needed until the whole PDF fits under 100KB. It reuses the same binary-search JPEG compression this site uses for its photo resizer, just aimed at a combined PDF instead of a single image, so quality loss is kept as small as possible for the size you need. If a very detailed or multi-image batch genuinely can't be squeezed under the limit without becoming unreadable, the tool tells you the smallest size it managed instead of silently failing. Everything runs locally in your browser.
How it works
- 1
Drop or select your images (JPEG, PNG, or WebP).
- 2
Click "Build PDF" — each image is embedded and the whole file is compressed toward 100KB automatically.
- 3
Download the finished PDF; if the target couldn't be hit exactly, the achieved size is shown.
Frequently asked questions
Will every image look the same quality after this?
Not necessarily — with multiple images, the 100KB budget is shared across all of them, so a batch of 5 photos gets roughly a fifth of the budget each. Fewer images means better quality per photo.
What happens if 100KB truly isn't enough?
The tool keeps compressing down to a safety floor rather than degrading images into pure noise, and if it still can't get under 100KB it shows you the smallest size actually achieved instead of guessing.
Why not just compress the images first and then combine them?
That's effectively what happens internally — the difference is this tool automates the trial-and-error for you and accounts for the PDF file's own overhead, rebuilding until the final combined file, not just the images, is under budget.
