- No install
- Trusted by 100M+ users
- Secure document processing
Shrink a PDF's file size so it's easier to email, upload, or store. In DocHub, compression is a download option on the Pro plan — you switch it on when you export the file.
How it works
01
Upload your PDF
Drag and drop your PDF into DocHub, or select it from your device. It opens in your browser — no software to install.
02
Turn on Compress File
Open the Download or export menu and, under PDF Options, tick Compress File. That's where compression is applied — as the file is exported.
03
Download your smaller PDF
DocHub compresses the file as it downloads, reducing its size (compression may slightly lower quality). Create a free DocHub account to save or share your PDF — compression is available on the Pro plan.

Emailing a PDF that's too big to send
When an attachment bounces for exceeding a size limit, compress it on export so it goes through.
Uploading to a portal with a size cap
Job applications, government forms, and course portals often limit file size. Compress the PDF to fit under the cap.
Saving space when archiving
Store scan-heavy PDFs as smaller files so they take up less room in the cloud or on your device.
Sharing a large document faster
A compressed PDF downloads and opens quicker for the person on the other end.
Sending several PDFs at once
Trim each file down so a batch of documents doesn't blow past an inbox's total size limit.

How do I compress a PDF in DocHub?
Open your PDF, go to the Download or export menu, tick Compress File under PDF Options, and download. DocHub compresses the file as it saves.
Is compressing a PDF free?
No. PDF compression is a Pro-plan feature. You can create a free DocHub account, but compression is a download option available on the Pro plan.
Will compression reduce the quality?
It can. DocHub notes that compression may reduce file quality — it trades some quality for a smaller size, which is usually fine for sharing and storage.
Where is the compress option?
It's the Compress File checkbox in the Download or export dialog, under PDF Options. Compression is applied at the moment you download or export the file.
How much smaller will my file be?
The reduction depends on the document — image-heavy PDFs usually shrink the most, while text-only files may change less. DocHub applies compression on export rather than letting you set a target size.
Can I compress a PDF on my phone?
Yes. DocHub runs in any modern mobile browser, so you can compress and download a PDF from your phone or tablet on a Pro plan.
