Frequently asked questions
Which conversion preserves transparency?
PNG and WebP preserve alpha. JPG does not - a transparent background becomes solid (white by default; pick a color in the tool).
Is my image uploaded?
Never. Conversion uses the browser Canvas API and stays entirely on your device.
What quality should I use for JPG or WebP?
75–85 is the standard sweet spot. Above 90 the file grows quickly for barely-visible quality gains.
How is this different from the image compressor?
Same underlying engine - this one is focused on format changes and batches; the compressor is focused on shrinking file size with quality tuning.
