Frequently Asked Questions
Is there a maximum PDF size I can compress?
No. Since compression runs locally in your browser, there is no server-imposed size limit. Large files are handled based on your device memory.
Why do other tools limit file size on free plans?
Server-based tools cap file sizes to control infrastructure costs and push users toward paid plans. Local processing eliminates that constraint entirely.
Will quality suffer when compressing large PDFs?
You choose the compression level — Low for best quality, Medium for balanced, High for smallest size. You control the tradeoff.
