PNM to JPG
- Step 1: Select your PNM files (PBM, PGM, PPM, or PNM) or drag and drop them. You may add up to 20 images, including large files. Optional: open Settings to set width, height, and JPG quality before converting.
- Step 2: The conversion starts automatically. We process your images quickly and in parallel. If you uploaded more than one file, we will prepare a ZIP containing all JPGs. Tip: keep JPG quality a bit higher for photos; lower values are fine for simple graphics.
- Step 3: Download your JPG or the ZIP archive. Note: JPG is lossy and 8-bit per channel. If your PNM had very high bit depth or pure black and white line art (PBM), JPG may introduce artifacts. For perfect edges, consider PNG; for compact photos, JPG is ideal.
You can upload up to 20 PNM images per batch. When you submit more than one file, your results are delivered as a ZIP. Need more than 20? Run another quick batch.
