This compressor rasterizes pages
Each page is turned into an image before being placed into a new PDF. Text is no longer selectable or searchable. That is why it can shrink scanned documents so much.

A smaller PDF, with no upload.
Compress scans and image-heavy PDFs by redrawing each page at a lower resolution. It is a real trade-off, explained plainly: smaller files, no selectable text.
No upload. No account. Files stay on your device. The processing happens in this browser tab—an unusual arrangement in a category full of upload forms.

Compress and compare
Add a PDF to begin.
Your PDF is opened and rebuilt inside this tab. There is no upload endpoint, no waiting in a queue, and no copy stored anywhere. How local processing works.
The short version
How it works.
No installer, no sign-up, and no second app to open. The work happens in the browser you already have, using the file already on your device.
-
Add a PDF
Choose the document and inspect the page count. This compressor works best on scans, photographed pages, and image-led reports.
-
Choose the quality
Set resolution and image quality, and optionally convert pages to grayscale. Lower settings create smaller files with softer detail.
-
Compare and download
Build the compressed copy, compare its size with the original, and download it only if the result works for you.
Fine print, without the runaround
Good to know.
Every tool has a boundary. These are the ones worth knowing before you start, so the result is not a surprise.
Not ideal for text-heavy contracts
For a text PDF that is already efficient, rendering can make the file larger and less useful. Keep the original for anything that must stay editable or accessible.
Check the result before sharing
Compression is one-way for the downloaded copy. Open it, zoom in on small print, and confirm that it is still legible before sending it to anyone who needs it.
Why is PDF compression different from image compression?
A PDF can contain text, vector drawings, fonts, and images. True PDF optimization needs to understand all of those. To keep this tool fully client-side, Lovely Tools renders each finished page as a single image, which is effective for scans but flattens text.
Will the compressed PDF still open everywhere?
Yes. It is a standard PDF containing one full-page image per page. Any normal PDF reader can open it. Links, form fields, and selectable text are not preserved.
How small will the file become?
It depends on what is inside. A 20 MB scan at high resolution can shrink dramatically. A 400 KB text PDF may become larger. The result screen shows the actual before-and-after sizes.
Is my PDF uploaded?
No. Pages are rendered to canvas and reassembled in your browser. Neither the original nor the compressed copy touches a Lovely Tools server.
