Frequently asked questions
Is the file exactly the chosen size?
The output aims to be at or below the limit, not exactly equal. JPEG quality and, when necessary, dimensions are reduced.
Is my content sent to a server?
No. Processing runs inside your browser. Optional editor recovery saves a draft on this device only. Read the privacy policy.
Will my original file be changed?
No. Downloaded results are separate copies. Open the finished output before sharing it or deleting an original.
