How it works
Lossless output
PNG preserves every pixel exactly. Choose PNG when you plan to edit further, or when JPG’s compression artefacts matter.
Expect large files
PNGs of iPhone photos are typically 5–15 MB each — several times the original HEIC. If file size matters more than pixel-perfect fidelity, use JPG.
Questions
Is PNG lossless?
Yes — PNG stores every pixel exactly. Use it when you need a perfect copy or plan to edit further. It produces much larger files than JPG.
Is my data private?
Yes. Everything happens in your browser. Open the Network tab to verify — no traffic during conversion.
Should I use PNG or JPG?
JPG is the right default for photos — it’s 5–10× smaller with no visible quality difference. Choose PNG only when you need lossless fidelity or plan further editing.
Can I use this offline?
After the page has loaded once, yes.
Why are the files so big?
PNG is lossless compression — it’s more like ZIP than JPG. Photos have too much random detail to compress tightly. That’s not Modime’s doing; that’s PNG.
