Changing DPI updates print metadata. It does not create new pixels.
For JPEG files, YesDPI rewrites the JFIF APP0 density field and/or EXIF resolution tags in place. For PNG files, it rewrites the pHYs chunk. Both are lossless, in-place metadata edits — the compressed pixel data is never touched, so the file opens exactly as before, just labeled with a different print density.
It rewrites the image's density metadata — the value a printer or design app reads to decide how large to print your pixels. It does not resample, sharpen, or add any pixels.
No. YesDPI edits the metadata bytes directly and never re-encodes JPEG or PNG pixel data, so there is no quality loss. WebP files are re-encoded to PNG because WebP has no standard editable density field; pixels are copied unchanged.
300 DPI is the standard for most professional and photo printing. 150 DPI can be acceptable for large-format prints viewed from a distance, like posters. 72–96 DPI is a screen convention, not a print target.
Yes — choose Custom in the DPI selector and enter any value from 1 to 65535.
