The tool opens with the output locked to PNG. Drag in your files, in any accepted format, and download them one by one or all together; the content never leaves your computer.
12 million pixels, well under 40 million.
8000 × 5000 = 40,000,000 pixels.
Goes past 40 megapixels. Shrink the image before converting.
The 16,384 px side is the maximum allowed, and the 16.4 MP area is within the limit.
The area is small, but the side goes over 16,384 px.
Transparency is filled with white, because the JPEG format does not support an alpha channel. If you need to preserve transparency, convert to PNG or WebP. The tool automatically warns you when this situation occurs.
No. PNG preserves what the image has, but does not restore detail lost to earlier compression. The gain is in editing and saving again with no new loss.
Because JPG discards detail to stay small and PNG keeps everything. If weight matters and the image is a photo, stay with JPG or WebP.
Yes. Drop as many files as you like, and download each PNG individually or all at once.
AVIF (not supported)
Converting a 6000px image without resizing is the classic mistake: the format changes but the file stays huge.
