One file at a time⚠️ Note: this process converts the pages into images, so the text inside the file will no longer be selectable or copyable after compression.
Toopec's PDF compression tool works by converting the file's pages into compressed images at an adjustable quality level, making it best suited for scanned documents or image-heavy files that are hard to shrink using traditional methods. Please note that the text will no longer be selectable or copyable after compression.

Frequently Asked Questions
How does the tool reduce the PDF file size?
The tool mainly works by re-compressing the images embedded inside the file and lowering their excess quality, since images are usually the main reason PDF files become bloated.
Does compressing the file affect text readability?
Selectable text inside the file is not affected by compression since it is data, not an image — the effect is limited to the quality of embedded images and graphics only.
How much can the file size shrink, roughly?
It depends on the file content; files with high-resolution or scanned images can shrink significantly, while purely text-based files shrink less since they are already well compressed.
Does it work with very large PDF files?
Yes, but very large files (hundreds of pages) may take longer to process depending on your device and browser's performance.
Are my files uploaded to a server?
No, compression happens entirely inside your browser, and no file is uploaded to an external server.
When should I use this tool instead of other compression options?
This tool is best suited for scanned files or files with many high-resolution images, where the compression effect is very noticeable in reducing size.
What quality level is recommended?
The medium level (60-75%) gives a good balance between size and sharpness for most uses; you can raise it if fine graphics or text are important.
