Perkforge
How it works
Choose or drop a JPG, PNG or WebP image. For cropping, choose a format and adjust the selection by dragging or entering pixels. Then set output dimensions and format, process and review the result before downloading. Nothing is uploaded and no account is required.
Useful to know
Reducing dimensions usually lowers file size. Enlarging an image adds pixels but cannot recreate detail that is missing from the original.
Private by design
Inputs, selected files and results stay inside your browser. Perkforge does not receive the content you process with this tool.
