Compress Image to 1MB
"Maximum file size: 1MB" is the classic upload wall — job application portals, government forms, CMS uploads, and support ticket attachments all use it, while your phone shoots 4–8MB photos. This tool re-encodes your image just under 1MB at the highest quality that fits, which for most photos means no visible change at all.
100% private — this tool runs in your browser. Your image is never uploaded to any server.

Frequently asked questions
Will compressing to 1MB reduce my photo's quality?
Rarely visibly. 1MB comfortably holds a sharp high-resolution photo; going from a 6MB camera file to 1MB mostly discards data your screen can't display anyway. The tool always uses the highest quality that fits.
How do I compress to 1MB without changing dimensions?
That's the default behavior: quality is adjusted first, and dimensions are only reduced if a file can't reach the target otherwise — which almost never happens at a 1MB budget.
What about PNG files over 1MB?
Upload them here — the tool converts to JPEG during compression, which is how you get a photo under 1MB. If you must keep PNG format (transparency), reduce dimensions instead with our resize tool.
