Compress PDF Without Losing Quality
Shrink PDF file size by up to 90% while keeping text crisp and images clear. Ideal for email attachments, form submissions, and web uploads where file size limits apply.
How It Works
Drop your PDF into the upload area
Pick a compression level — light, balanced, or maximum
The file is re-encoded with optimized image settings and font deduplication
Save the smaller PDF — same content, fraction of the size

"Compress this PDF to under 5MB"Frequently Asked Questions
How much smaller will my PDF get?
A 50 MB photo-heavy report often comes down to 5-8 MB. Text-only documents with few images typically shrink 30-50%. Scanned pages see the biggest drops because each page is a full-size image.
Does the text stay readable after compression?
Vector text (the kind you can select and copy) passes through untouched — compression only targets embedded images. Even at maximum compression, text remains sharp and fully searchable.
Can I set a target file size?
Tell DocuHub your target — for example, "make it under 5 MB" or "small enough for Gmail's 25 MB limit" — and the compression level adjusts to hit that number as closely as possible.
Do hyperlinks and bookmarks survive compression?
Links, bookmarks, form fields, and the table of contents all remain intact. Only the raster image data inside the PDF is re-encoded.
What's the upload limit?
You can upload files up to 100 MB. For anything larger, split the PDF first using the Split tool and compress each part separately.
Do I need to create an account?
No account, no sign-up form, no trial period. The compressor is free to use as often as you need, and the output never includes a watermark.
