常见问题
Are my images uploaded?
ToolGrid image tool code uses browser APIs such as Canvas and local file decoding. Selected image files are not submitted to a TOOLGRID processing endpoint.
Which image formats can I convert?
The Image Format Converter accepts JPG/JPEG, PNG, and WebP input, with AVIF input attempted when your browser supports it. Output is limited to PNG, JPEG, and WebP.
Can I convert multiple images at once?
Yes. Select or drop multiple files, choose the output format and quality, then download each converted result from the results list.
Will converting improve image quality?
No converter can restore detail that was already lost. JPEG to PNG can create a larger file without improving quality; use optimization tools when your goal is smaller file size.
What happens to transparent PNG or WebP images when converting to JPEG?
JPEG does not support transparency, so the converter composites transparent pixels onto the background color you choose, defaulting to white.
