Frequently asked questions
How do I compress a PDF to 1MB?
Drop your PDF above and press Compress. We first try a lossless clean-up; if the file is still over 1MB, we lower image quality step by step and keep the best-looking version that is under 1MB.
What if my PDF can't get under 1MB?
Very long PDFs or pages full of photos may not fit. You'll get the smallest version we could make. Try removing pages you don't need with Remove PDF Pages or Split PDF, then compress again.
Will the text still be readable?
Yes — we pick the highest quality that fits. To reach small sizes, pages may be saved as images, so text stays readable but can't be selected or searched in the compressed copy.
Are my documents safe?
Nothing is uploaded. Your files are processed right here in your browser and never leave your device, so we never see them.
Is it free to compress PDF to 1MB?
Yes. There is no sign-up, no watermark and no daily limit.
