Who this guide is for
| Role | Typical use |
|---|---|
| Developer | A PDF specialist uses Compress PDF during sprint demos to show shrink pdf file size on real customer samples (redacted) without leaving the browser. |
| Reviewer | A technical writer embeds /tools/compress-pdf links in onboarding docs so new hires reproduce formatting steps on day one. |

| Student | A student compares Compress PDF output with textbook examples to understand how pdf transformations behave on edge cases. |
How to use it
- Open https://devswallet.com/tools/compress-pdf. Navigate to /tools/compress-pdf and confirm the header shows Compress PDF with the PDF category badge.
- Skim the tool description: Government portals and legacy email gateways still enforce 5–10 MB limits; compress PDF targets readable text documents rather than photo yearbooks.
- Prepare input according to the on-screen labels, shrink pdf file size often fails when delimiter or encoding assumptions differ from your source system.
- If optional settings exist, expand advanced panels and note defaults;
- Run the primary action and wait for completion indicators, worker-backed tools may take longer than instant client-side utilities.
- Validate output against a known-good sample before processing hundreds of rows in bulk.
- Copy or download results using the built-in buttons rather than selecting from the DOM, which can miss hidden whitespace.
- If output is incorrect, reduce input size to a minimal reproducer and retry; this isolates bad data from tool bugs.
