JPEG to PNG
PNG is lossless — but it preserves what has already been lost: the JPEG artefacts carry over and the file grows. It makes sense when editing comes next or transparency is needed. On our corpus a 1200×800 frame in PNG averages 1489 kB for a photograph and 26 kB for flat graphics — 1318% of what JPEG takes at the same quality.
How to do it
- Pick a JPEG file, drag it in, or paste with Ctrl+V
- The format is already set to PNG
- Take the finished file. Several at once works too — you get a ZIP
Frequently asked questions
- How much smaller will the file be?
- On our corpus a 1200×800 frame in PNG averages 1489 kB for a photograph and 26 kB for flat graphics — 1318% of what JPEG takes at the same quality.
- Will PNG improve the quality?
- No. PNG losslessly preserves what has already been lost — the JPEG artefacts get written pixel for pixel. The file grows too: on photographs PNG comes out roughly thirteen times larger than JPEG. Reach for PNG when you need transparency or further editing.
- Will PNG open everywhere?
- Yes. PNG opens anywhere, from a browser to a printer.
- Why do phone photos sometimes come out sideways?
- Because the orientation lives in a separate EXIF tag rather than in the pixels, and most converters ignore it. Here the tag is read and applied before anything else, so a portrait shot stays portrait.
