What changes
Both formats are lossless, so the quality doesn’t change.
The file size stays about the same.
PNG supports transparency and PPM doesn’t, so there’s nothing transparent to lose: the background is already solid. What you gain is the option to remove the background later, which a PPM doesn’t allow.
Your browser may not be able to open PPM files, but the converter reads the file itself, so it can still convert it.
When it’s worth it
Choose PNG for: Logos, screenshots, and graphics. Keeps every pixel and supports transparent backgrounds.
Stay with PPM for: Teaching, testing, and image-processing pipelines.

Questions
Does converting PPM to PNG lose quality?
No. Both formats are lossless.
What is the PNG format?
Lossless image format from 1995, standardized as ISO/IEC 15948. It compresses with Deflate and supports an alpha channel and 8 or 16 bits per channel, which is why it’s the default for screenshots, logos and anything that has to stay sharp.
What is the PPM format?
The RGB member of the Netpbm family, created in the mid-1980s and still around because it’s trivial to read: a short ASCII header and then plain pixel values. It’s a favorite for testing image tools.
Are the files uploaded?
No. The file is opened in this tab, converted here and saved from here. There’s no account and no watermark.
How many files can be converted at once?
Up to 200 per batch and about 2 GB per file, within the memory this device has available.
