Guide
Yes. The public tool is free to use in your browser.
No. This tool runs locally in your browser, so selected files or pasted input are not uploaded to Convurter.
This does not compress the PDF. Use Compress PDF only when size reduction is needed and review output quality. Review the final output before using it in production work.
Good next steps include Compress PDF, PDF File Size Inspector, and PDF Image Density Report.
Workflow fit
If you are unsure, start from the PDF chooser and pick by task: inspect, organize, compress, convert, print, compare, or flatten.
Use these when the current result is only one step in a longer task.
Use these when the output needs checking, cleanup, comparison, compression, or a final share-ready pass.
