About 100KB
100KB is tiny for a PDF. One or two simple pages will fit; longer scans may need a higher target.
The tool rebuilds each page as a compressed image until the whole file fits under 100KB. Documents with many pages need a higher target than short ones.
Tips for best results
Best for scanned documents, forms and image-heavy PDFs. Pages are converted to compressed images, so text in the result cannot be selected or searched. Keep your original file as a backup.
Frequently asked questions
Is it free?
Yes, completely free with no sign-up.
Are my files uploaded anywhere?
No. Compression happens inside your browser and your file never leaves your device.
Why is my result slightly under the target?
The tool finds the highest quality that still fits under the limit you chose.
