Why Is My PNG File So Large?
PNG isn’t “broken” when it’s large — it’s doing lossless work. Photos belong in lossy formats; sharp graphics belong in PNG.
Problem: A PNG export is many megabytes and slow to upload or email.
Solution: For photos: convert PNG → JPG or WebP (and resize). For logos/UI: keep PNG or use SVG; optimize/minify when needed.
Photos vs graphics
Camera-like images compress poorly as PNG. Flat UI and text stay crisp in PNG but photos should move to JPG/WebP.
Resize before converting
A 4000px PNG in a 1200px slot wastes bytes. Resize, then convert or compress.
Transparency note
JPG cannot keep alpha. If you need transparency, use PNG, WebP, or SVG — not JPG.
Fix it in three steps
- Decide photo vs graphic. Photos → JPG/WebP. Logos/UI → PNG/SVG.
- Resize if oversized. Match real display dimensions.
- Convert or compress. Use PNG → JPG/WebP or the PNG compressor.

FAQ
Why is my PNG file so large?
PNG is lossless — photos saved as PNG stay huge. Convert photos to JPG or WebP (after resizing). Keep PNG for logos, UI, and transparency.
Should I always avoid PNG?
No — PNG is excellent for screenshots, UI, and logos. It’s a poor default for photographs.
