Compress PDF online free with SavyTools and shrink a large PDF so it fits email attachments and upload forms without losing readability. If you need to compress PDF for email — a resume, an application, or a scanned form that keeps bouncing back — the tool runs entirely in your browser and shows the before and after sizes, so you can see exactly how much smaller your file became.
Your file is processed in your browser, so it is never uploaded to a server. The tool shows the before and after sizes, so you can see exactly how much smaller the file became.
How to Use
- Upload the PDF you want to shrink.
- Choose a compression mode: a gentle re-save that keeps everything as it is, or a stronger rebuild for a smaller file.
- Run the compression and compare the before and after file sizes.
- Download the compressed PDF and check that it still reads well before sending it.
Frequently Asked Questions
How much can a PDF be compressed?
It depends on what is inside the file. PDFs full of large images usually shrink a lot, while text-only PDFs are already small and shrink less. The tool shows both sizes so you can judge the result yourself.
Will quality drop?
The gentle re-save mode keeps your content unchanged. The stronger rebuild mode can reduce image quality to reach a smaller size, so check the result before you send it if image sharpness matters.
Can I compress a PDF for email?
Yes, that is one of the most common uses. Compress the file, check that the new size is under your email provider’s attachment limit, and then attach the compressed version.
Tips
Start with the gentle re-save mode and check the new size first; it is enough for many files. If the file is still too large for your email or upload form, run the stronger rebuild mode and compare again. Always keep the original PDF until you have checked the compressed copy, especially if the document contains small text or detailed images.
