Best practices for cleaner results
- Group related files into folders before converting so your output stays organized and easy to archive.
- Use higher resolution presets when you know the result will be printed, zoomed in, or reused in design tools.
- Keep an unedited copy of your original PDF files for audits, record‑keeping, or compliance workflows.
- Combine this tool with other File Studio actions like compress, merge, or split to streamline entire document pipelines.

FAQ
Frequently asked questions
Will compression make my PDF unreadable?→
You can preview compression levels and choose a preset that keeps text sharp and images clear while still shrinking file size.
Can I undo compression later?→
Compression is not reversible, so File Studio always keeps your original PDF separate from the compressed version.
How small can I make a PDF without ruining quality?→
That depends on the content, but the balanced profile is a great starting point. You can experiment with more aggressive modes while checking a quick preview first.
Does compressing a PDF remove searchable text?→
No. File Studio keeps text layers and vector shapes intact wherever possible, only targeting images and embedded assets for compression.
Is there a recommended preset for emailing PDFs?→
Yes. The balanced profile is designed for emailing PDFs: it keeps text and key graphics clear while dramatically reducing file size.
Can I see how much smaller my PDF will be before saving?→
File Studio shows an estimated output size so you can tweak compression settings until they meet your limits.
