🔒 Files never leave your deviceCompress a PDF to email size — Free, and Nothing Is Uploaded
Enter email size as your target and the compressor works out the rest — testing quality settings against your own pages until it finds the best one that fits. Built for mail servers that bounce anything much over 10 MB, and recipients who quietly hate large attachments.

How to compress a PDF to email size
- Open the editor and choose your PDF.
- Click Export and select Compressed PDF.
- Type emailsize into the target file size box.
- Optionally tick grayscale for extra savings.
- Click Export — the file is built to fit email size.
Tip: Aim for 1 MB. It sails through every mail server, downloads instantly on mobile data and still reads well.
Why a target size beats guessing at quality settings
Almost every compression tool asks you to pick "low, medium or high" and then hope. If the result is still too big you go back and try again, and if it comes out far smaller than needed you have thrown away quality for nothing. Neither is what you actually wanted, which was simply a file under email size.
This tool inverts that. You state the limit; the software runs the search. It renders sample pages from your own document at a ladder of resolution and quality combinations, measures the real bytes each produces, projects the total across your page count, and then builds the file at the highest quality that still fits. If the finished file lands above target — which occasionally happens when later pages are denser than the samples — it automatically drops a step and rebuilds rather than handing you something that misses the limit.
What to expect from the result
In testing on a four-page scanned document, targets were hit at between 89% and 95% of the requested size — using the available budget rather than overshooting downward and needlessly softening the text. Text-heavy scans compress dramatically; documents that are already efficient vector text may barely shrink, and the tool says so instead of pretending.

Frequently asked questions
How do I compress a PDF to email size?
Open your file, choose Compressed PDF in the export dialog, enter email size as the target size and export. The tool tests quality settings against your document and picks the best one that fits.
How does it know which quality to use?
It samples representative pages across a ladder of resolution and quality settings, projects the finished size for your document, then builds at the highest quality that fits your target — and steps down automatically if the real file comes out larger than projected.
What if my PDF cannot reach email size?
Then it tells you. Rather than silently producing something larger, the tool reports the smallest size it could reach and suggests grayscale or removing pages. A hundred-page colour scan cannot become a tiny file without losing something.
Is my document uploaded to compress it?
No. The sampling, the compression and the export all run in your browser. The file never leaves your device.
