Frequently asked questions
When should I use JPG vs PNG vs WebP?
Use JPG for photographs and complex images where small file size matters. PNG is best for graphics with transparency, sharp text, or flat colors — it is lossless so nothing is lost. WebP offers the best of both: smaller files than JPG with optional transparency like PNG, but older browsers may not support it.
Does the quality slider affect PNG output?
No. PNG is always lossless, so the quality slider has no effect when converting to PNG. It only applies to JPG and WebP, which use lossy compression.
Will converting between formats change my image dimensions?
No. Format conversion only changes the encoding — the pixel dimensions, aspect ratio, and visual content remain identical.
Is there a file-size limit?
There is no enforced limit since everything runs in your browser. However, very large images (above 50 megapixels) may be slow to process depending on your device.
