Can I compress a PDF to exactly 100 KB?

The tool iteratively adjusts image quality and page resolution to aim below 100 KB. Exact output depends on the number of pages and the complexity of the document.

Are my PDF files uploaded to a server?

No. Processing happens locally in the browser and the selected PDF is not intentionally uploaded by this tool.

Why can very small targets reduce readability?

A strict limit such as 50 KB leaves very little data for multi-page documents, so the tool may need to lower image quality and resolution.

Will selectable text and links remain in the compressed PDF?

For strong target-size compression, pages are flattened into optimized images. Selectable text, links, forms, layers and interactive elements may not remain interactive.

Important quality information

The feasibility of a target depends on page count, dimensions, colour, photographs and scan complexity. A one-page certificate may fit under 100 KB with readable quality, while a long colour document may require a higher target. For strong reduction, this tool reconstructs pages as compressed images, which can remove selectable text and interactive elements.

Frequently Asked Questions

Can this tool compress a PDF under 50 KB?

Yes, it will attempt to do so. A 50 KB limit is extremely strict, so it works best for one-page documents and may require low resolution.

Can I set my own PDF size?

Yes. Select Custom Size, enter a value, and choose KB or MB.

Does the tool guarantee the exact target?

It aims to produce a file below the selected maximum. Some complex or long documents may not reach a very small target while remaining technically valid.

Is this suitable for government and job portals?

Yes. It is specifically designed for documents that must remain under a stated upload limit. Always open and check the downloaded file before final submission.

Are password-protected PDFs supported?

Encrypted or password-protected documents may not open. Remove the password using an authorized method before compression.
