What makes a PDF shrink
A PDF made from scanned pages is mostly pictures, so it has the most to give. A PDF exported from a word processor is mostly text and vector shapes, which are already compact, so savings are small. Embedded images are where Timamu finds most of the weight.
Typical results by kind of PDF
- Scanned pages: the largest savings, because each page is one big picture.
- Photo-heavy brochures and decks exported to PDF: large savings.
- Text-only contracts and invoices: small savings.
- PDFs already optimised by another tool: small savings.
Levels and modes
- Safe, Balanced and Strong are the compress levels, and all three are Free.
- Protect Quality favours how the pages look.
- Reach Target works toward a size you enter.
- Smallest Possible goes as far as a valid file allows.
Steps to compress a PDF
- Choose the PDF in Timamu Web. PDFs up to 100 MB are accepted on Free and Premium.
- Pick a level or mode, and enter a size if you use Reach Target.
- Preview the prepared copy before saving.
- Download it. The original PDF is never replaced.
Check the result before you send it
Safe is the gentlest of the three levels and Strong goes furthest. Open the preview and read a page with small print, a signature block and any photo. If text looks fuzzy, step back from Strong to Balanced or enter a larger target. Page count and page order do not change.
Questions
Why did my PDF barely shrink?
A text-only or already optimised PDF has little image data to reduce. Timamu keeps the result valid and reports the size it reached rather than forcing a broken file.
Which level suits a scanned document?
Start with Balanced. Move to Strong when the size still matters more than sharpness, and check the preview before you save.
Can I combine PDFs and shrink them together?
Yes. Merge PDF joins several files and compresses them in one step.
Is there a size cap?
PDFs up to 100 MB are accepted on Free and Premium. Larger files are declined before processing and the original stays untouched.
