UNDERSTAND YOUR FILES
PGM vs. JPEG: what changes?
PGM is the Netpbm portable grayscale format.
A widely supported photographic format. JPEG uses lossy compression and cannot represent transparency.
JPEG output is convenient for photographs, older upload forms, and tools that require JPG files. Choosing an output format changes how another app reads the file; it does not restore detail missing from your source.
Which settings should you choose?
Try Balanced (88%) first, inspect the preview, then switch to Compact for a smaller result or Detailed for greater fidelity. These are export quality settings, not promises of a particular compression ratio.
Your files and privacy
Your selected file is converted on your device. You can download the new file while keeping the original unchanged.
Some formats work differently across browsers and devices. Check the converted result before using it for important work. Advertising and other optional website services may have separate privacy practices.
Format compatibility and limitations
PGM P2/P5 grayscale inputs are supported, including 16-bit maxval samples. JPEG cannot preserve transparent pixels: transparent areas become white. It uses lossy compression.
Actual output behavior depends on the input file, your browser, device resources and the converter engine. Check important files before sharing or replacing them.
JPG and JPEG are the same image format. This tool accepts .jpg and .jpeg input and uses .jpg for exports.
HELP & ANSWERS

Does changing formats improve the original quality?
No. Re-encoding may lose detail, and cannot restore information that the source file no longer contains.
