Image conversion10-part series
Select PNG, JPEG or WebP and review transparency and exported properties.
Know the feature scope
Re-encode supported PNG, JPEG and WebP in the browser. JPEG fills transparency with white; review actual output support without assuming original metadata or animation is retained.
Series contents
10 guides- 01
Prepare web images: resize, compress and choose a format
Prepare PNG, JPEG and WebP images for publishing. Distinguish pixel dimensions from file size, choose transparency and quality settings and inspect the exported result before replacing the original.
- 02
Choose PNG, JPEG or WebP for the intended use
Format choice goes beyond size. Review photos, text, transparency and destination support together.
- 03
Review white backgrounds when converting transparent PNG to JPEG
JPEG output fills transparency with white. Compare a logo’s result on its intended dark background.
- 04
Verify WebP support and quality with actual output
WebP is an output candidate. Check browser and destination handling, then compare size and quality.
- 05
Check width and height after format conversion
Conversion and resizing are separate features. Verify retained pixel dimensions before publishing.
- 06
Distinguish renaming an extension from actual conversion
Renaming a file to .jpg does not turn its data into JPEG. Verify that you use genuinely encoded output.
- 07
Review animation-image conversion results
The current conversion uses a static canvas export. Check whether an animated source loses movement.
- 08
Review metadata assumptions after re-encoding
The output is recreated from canvas. Do not assume all source capture or authoring information remains.
- 09
Create a final review checklist for converted images
Verify that the export opens and displays correctly at its destination. Record format, dimensions, background and readability.
- 10
What to check when an image export looks wrong
Diagnose a larger file, changed transparency, unexpected dimensions or a failed image export. Compare the source with the output and choose settings that fit its purpose.
