About PDF Compressor
Informational only, not professional advice. Report an error.
Upload limits on job portals, school systems, and email often block large PDF scans and slide decks.
PDF Compressor runs locally in your browser with three presets: light structure cleanup (no image recompression), balanced image recompression, or maximum size reduction.
Output is best effort. Open the download and compare it to your original before you submit to a portal, court, or employer.
Use Image Compressor or Image Format Converter first when your workflow starts from photos instead of an existing PDF.
Common use cases
- Solve quick everyday math or timing tasks without installing an app.
- Double-check unit conversions for recipes, travel, fitness, or homework.
- Count days between dates for planning, deadlines, or simple schedules.
- Generate random numbers or run a browser timer for games, meetings, or focus blocks.
- Use Image Compressor when your next step needs a related calculation on the same page tab.

Common mistakes and fixes
Pasting production secrets, tokens, or personal data into any browser tool.
Fix: Use redacted samples in development. Client-side processing still leaves data in browser memory and history.
Mixing date-only and datetime fields when the UI expects calendar dates.
Fix: Match the input style shown on the tool. Date-only mode counts calendar days, not clock times.
Picking the wrong unit category (weight versus volume, miles versus km).
Fix: Confirm unit labels before copying a result into another app or spreadsheet.
