Get your PDF under 300KB with the best readable quality that fits.
108pdf first tries a lossless rebuild. If the file is still above 300KB, pages are re-rendered as optimised images, starting at high resolution and stepping down until the file fits. You get the sharpest version that is under 300KB.
300KB is a common limit for caste certificates, mark sheets and ID proofs on government portals. For best results, keep documents to 1 to 3 pages.
Compress PDF to 300KB runs entirely in your browser. Your file is opened by your own device, processed there and saved back to you, so it is never uploaded to a server and never stored by us. That makes it safe for ID cards, exam forms, contracts and any other document you would rather keep private.
There is no account to create, no watermark on the result and no daily limit. You can process as many files as you like, one after another, and the tool keeps working even on a slow connection once the page has loaded.
If the result is not what you expected, change the options and run Compress PDF to 300KB again on the same file. Nothing is lost, and your original file is never touched. Use the related tools below to continue the job, for example to resize, convert or merge the output.
Remove pages you do not need with Delete PDF Pages, or split the document and upload the parts separately. Very long scans may not fit small limits while staying readable.
No. 108pdf processes this file inside your browser using your own device. Nothing is sent to our servers, so there is nothing to delete afterwards and nothing that can leak.
Yes. It is free with no sign-up, no watermark and no daily limit.
