Reduce PDF Size
Give a target size and the tool tries progressively stronger settings until it gets there.

Nothing is uploaded — your file is processed on this device.
Compression works by re-rendering each page as an optimised image, which reliably shrinks scans and image-heavy files. Text stops being selectable in the result — use Optimize PDF when you need to keep the text layer.
How to reduce pdf size
- 1Upload the PDF.
- 2Enter your target size in kilobytes.
- 3Run it — the tool reports whether the target was met.
About this tool
Government portals, job applications and university submissions frequently specify an exact limit — under 1 MB, under 500 KB — and reject anything larger with no explanation of how to fix it. Guessing compression levels until something fits is frustrating.
Here you state the limit instead. The tool renders the document at successively lower resolutions and qualities, checking the size after each pass, and stops as soon as it is under your target. If even the lowest readable setting cannot reach the number, you are told the smallest size achieved rather than handed an unreadable file.
What it's good for
- Meeting a strict 1 MB upload limit on an application form.
- Fitting a scan into a size-restricted email system.
- Preparing documents for a portal with a per-file cap.
- Shrinking a batch of scans to a consistent budget.

Questions people ask
- What if it cannot reach my target?
- You still get the smallest readable version, plus a note of its actual size.
- How many kilobytes is 1 MB?
- 1024 KB. For 2 MB enter 2048.
- Will pages stay sharp?
- The tool stops as soon as the target is met, so it uses the highest quality that fits.
