Will my fonts break?
Generally no—this isn’t a print-to-PDF hack. Embedded text stays text; rasterized pages lose detail first.

How to Compress a PDF

Choose compression level: Low, Medium, or High.
-
ConvertFloor processes the file and reduces its size.
-
Download the compressed PDF. Your file is not stored.
What happens when you use Compress PDF
Pick Low, Medium, or High—Adobe’s engine rewrites the PDF so attachments stop tripping 8–10MB walls. Text usually survives fine; photos and scanned pages take the hit first. One file, 10MB max in, smaller PDF out. Nothing is kept after you download. I’d default to Medium unless I’m emailing a deck full of screenshots—then I might brave High and eyeball the result.
Half the time people need PDF Merge right after Compress PDF—same workflow, different output.
Two writes worth bookmarking: how compression actually works on PDFs and when merged PDFs blow past email limits.
If this isn’t the last stop, people often chain PDF Merge then PDF Split —same file, different headache.
When Compress PDF is the right call
- The merged bundle from PDF Merge just laughed at your mail server’s limit
- A form portal caps uploads and you’re 200KB over with no patience left
- You’re archiving years of scans and want less disk, not a museum-quality photo book
- You already know the recipient opens on a phone—lighter files actually open
Formats
In: PDF only. Single file, max 10MB. Requires Adobe PDF Services.
Out: Compressed PDF. Same format; reduced file size.
Uploads are processed for conversion only—we are not building a library of your documents.
When it goes sideways
- Barely shrank: Text-only PDFs don’t have much fat. Image-heavy ones respond better—try High if you can tolerate softer pictures.
- Looks mushy after High: That’s the trade. Step down to Medium or keep an uncompressed master somewhere safe.
- Rejected / timeout: Passwords and corrupt files break the pipeline. Unlock in a reader first. Still stuck? Stay under 10MB.
- Hit the daily cap: Guests: 7/day, signed-in 15/day—clock resets midnight. Logging in is the boring fix.
FAQ
Merge then compress or the other way around?
Merge first to see real size, then compress the combined file once.
Same as “print to PDF”?
Different stack—here you’re optimizing an existing PDF, not re-rendering from Word.
Mobile?
Works in the browser; huge files still prefer Wi‑Fi.
Stored anywhere?
No—download and it’s gone from our side.
