Frequently Asked Questions
Why convert JPEG to PNG?
JPEG (Joint Photographic Experts Group) uses lossy compressed encoding and is best for photographs, web images, and social media where smaller file size matters more than perfect quality. PNG (Portable Network Graphics) uses lossless encoding and excels at graphics with sharp edges, text overlays, screenshots, and images requiring transparent backgrounds. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
Does JPG to PNG improve quality?
No — PNG preserves exactly what the JPG held, blocking further degradation through edit cycles. Convert once at workflow start, not repeatedly.
When is PNG actually better?
Graphics with text, screenshots, and transparency work — plus any multi-save editing pipeline. Photos for web stay JPG/WebP for size.
File size shock?
Expect 3–5x larger files — PNG compression can't undo JPEG entropy. A 500 KB photo becomes ~2 MB PNG; normal and worth it for editing.
Do source photos upload anywhere?
No — conversion runs locally in your browser on Canvas. Saves never touch a meter — downloads on local tools are unlimited.
