Convert PNG to JPG online in seconds. Also converts WebP, AVIF, JFIF, BMP, TIFF and GIF in any direction. Transparency is flattened onto a background colour you choose rather than silently onto black. Up to 100 images per run, with resize and quality.
Converts PNG, JPG, JFIF, WebP, AVIF, BMP, TIFF and GIF images to JPEG, PNG, WebP, AVIF, TIFF or
BMP with ImageMagick.
Converts up to 100 images per run. Every result is stored under its own filename and the set
is packed into one images.zip, which is what OUTPUT and run-sync return. A single image is
returned as the image itself. Past 192 MB of output the run writes a MANIFEST.json listing the
results instead, because the archive is assembled in memory.
Accepts the sources as an array of URLs or uploads in files, a single URL in file, or base64.
A file that fails does not stop the batch. Each file gets its own dataset record with an ok
flag and, when it failed, a plain-language reason; the run fails only if nothing converted.
Records are pushed as each file finishes, so an interrupted run keeps what it had.
De-duplicates output keys, so two folders that both hold an IMG_0001.png produce
IMG_0001.jpg and IMG_0001-2.jpg rather than one silently replacing the other.
Caps a run at 100 files, 512 MB of input, 100 MB per file, 100 MP per image and 2 GP overall, and
gives every download a 120 second timeout, refusing with a message that names the limit rather
than timing out halfway through.
Flattens transparency onto a chosen backgroundColor, defaulting to white, whenever the output
format cannot store an alpha channel. A colour ImageMagick does not recognise fails the run
instead of silently producing a black background, which is what it does when left alone.
Reads the file header rather than the extension to identify the source format, so a .jfif is
reported as the JPEG it is, and a PDF, SVG, HTML error page or video file is refused by name
instead of producing an ImageMagick delegate error.
Applies EXIF orientation, optional downscaling, optional conversion into sRGB, and optional
stripping of EXIF, XMP and IPTC while keeping the ICC colour profile.
Converts the first frame of an animated GIF, animated WebP or APNG, with a warning, rather than
writing one file per frame.
Built on Debian trixie: bookworm's libheif 1.15.1 drops the alpha channel in both directions
through AVIF, so a transparent AVIF converted to JPG came out black.
