Questions
FAQ
Privacy, quality, and what to expect from local compression.
Why do I need a PDF under 500KB?
Many online forms and inboxes cap attachments at 500KB. SizePDF aims for that target locally.
Is my file uploaded?
No. Everything runs in your browser. Files never leave your device.
Will text stay selectable?
Strong compression turns pages into images, so text is usually not selectable.
What if it cannot reach 500KB?
Download the closest result, try Smaller file, or use 1MB if a larger file is allowed.
