Compress PDF to 300KB
Reduce a PDF to a target size such as 300 KB. The file is processed in your browser and never uploaded.
How it shrinks the file
Each page is turned into an image and saved at the best quality that still fits your target. Text pages compress very well, and photo-heavy PDFs need more reduction.
Good to know
Pages become images, so the text in the result cannot be selected or searched. Keep your original for that. Typical uses are email size limits and online application forms.
Compress PDF to 300KB FAQ
How does Compress PDF to 300KB work?
Each page is rendered as an image and re-saved as a JPG at a lower quality and, if needed, a lower resolution. The tool tries several quality levels in order and stops at the best-looking one that fits your target size.
Will I still be able to select text in the compressed PDF?
No. Because pages become images, the text in the result cannot be selected, searched or copied. Keep your original if you need searchable text.
Can I compress to a size other than 300 KB?
Yes. Type any target size in KB. Very small targets on long documents may not be reachable, and the tool then gives you the smallest file it could make.
Is my PDF uploaded to a server?
No. The PDF is processed inside your browser and never leaves your device.
What if my PDF is password protected?
Remove the password first. Encrypted files cannot be read by the tool.
