JPG to PGM
- Step 1: Upload one or more JPG images. Drag and drop them into the upload area or click to choose files. You can add up to 20 at once, and large files are welcome. If you need a specific output size, set the width and height in the settings below before converting.
- Step 2: Conversion starts automatically. We turn your JPGs into standard PGM grayscale images within seconds. Color photos are mapped to gray tones. Tip: Use the highest quality JPG you have to reduce visible compression artifacts in the PGM.
- Step 3: Download your PGM files. If you uploaded more than one image, your results are packed into a single ZIP for easy saving. Resizing you selected is applied to every file.
You can upload up to 20 images at once. Multiple results are delivered as a single ZIP.
