Bulk compress images FAQs
How many images can I compress at once?
As many as your browser and device memory can handle — no artificial 20-file server cap.
Is bulk compress free?
Yes. Free, no account, private on-device processing.
Does bulk upload images?
No. Every image is compressed in your browser.
Do you upload my files?
No. GroundPDF processes files entirely in your browser with WebAssembly. Files never leave your device — nothing is uploaded to a server.
Is it free?
Yes. Free to use with no account and no daily limits.
Which devices and browsers work?
Any modern browser with WebAssembly support: Chrome, Firefox, Safari, and Edge on desktop or mobile.
How is this different from iLovePDF or Smallpdf?
Those tools upload your files to the cloud. GroundPDF runs on your device (on the ground, not in the cloud), so your documents stay private by design.
