Compress PDF to a size limit

Choose a PDF size limit such as 100 KB, 200 KB, 500 KB or 1 MB. Try bounded compression and check the actual output against your target.

Run this workflow

One PDF file · up to 50 MiB each, 100 MiB total · up to 300 pages. Files stay on your device.

Size limitUnit

KB = 1,000 bytes. MB = 1,000,000 bytes. Up to three attempts; meeting the limit is not guaranteed. A file already within the limit is returned unchanged.

I allow compression to create image-based pages. Searchable text, links and form fields may be lost. If no attempt is smaller, keep the original PDF. You can check the size without consenting; larger files require consent before compression.

How it works

Try compression for your size limit
Check the final byte count

Use this when an upload has a stated size limit. Unlike a generic quality setting, this workflow measures the output against the limit you enter. Numeric targets share this one page because the task is the same. Check your destination’s current limit and units before choosing a target; a country or application-specific requirement is not assumed.

Check your result

Compare the exact output bytes with the target. Target met means at or below the entered byte limit.
Open the downloaded PDF and inspect every page, especially small text, signatures and diagrams.
If the target is not met, try a larger permitted limit or extract only the necessary pages. The smallest available result is still downloadable.

Supported files and limits

One readable, unencrypted PDF, up to 50 MiB and 300 pages. KB means 1,000 bytes and MB means 1,000,000 bytes. A file already within the target is returned unchanged. Otherwise, up to three raster-compression passes reduce resolution and JPEG quality; text, links and editable forms may be lost. The smallest result is kept, never a larger file. Reaching the target is not guaranteed, and an upload service may apply other requirements.

Can every PDF be compressed to 100 KB or 200 KB?

No. Long documents and detailed scans may remain too large after the bounded attempts. This page explicitly reports Target not met instead of labelling that result a success. A text-only PDF may already be smaller than any rasterized version, so the original is retained. Choose the minimum quality trade-off you can accept and inspect the result.
