PNG to JPG, done correctly
The conversion is a re-encode: each PNG decodes to raw pixels, draws onto a canvas, and re-encodes as JPEG at 92% quality. The detail separating a correct converter from a careless one is transparency — JPG cannot represent it, so transparent pixels are composited onto pure white, the right default for screenshots, scans, product shots and photos headed for documents or the web.
Batch handling is built in: queue any number of files, convert all with one click, save each from its card or everything via Save all. Nothing uploads, so there's no size anxiety and no privacy trade-off.
Where the bytes go — and where quality goes
The numbers are content-dependent. A 24-bit screenshot of 1.5 MB typically lands at 250–400 KB as a quality-92 JPG; a photographic PNG of 8 MB drops to well under a megabyte. The cost is ringing around hard edges, which stays invisible in photographs but becomes faint mosquito noise around small text and one-pixel UI lines even at 92. For interface screenshots, diagrams and anything with type, PNG or WebP remains the better format; for photos, product shots and scans, JPG is the right trade. Semi-transparent shadows and glows are composited against white during flattening, so an overlay designed for a dark background will look wrong — flatten it onto the intended color in an editor first.
Output files keep their base name with a .jpg extension, so photo.png becomes photo.jpg beside the original, and Save all triggers one download per file rather than a ZIP — allow multiple downloads when the browser asks the first time. Keep the PNGs as masters: JPG re-saves compound loss, and this conversion is a one-way door. The pixels are decoded and re-encoded through a canvas, which drops the PNG's text chunks and any ICC profile and writes sRGB, using the browser's own encoder at quality 92. For a bigger squeeze on the same photos, run the JPGs through the JPEG Compressor afterwards, which re-encodes with mozjpeg and typically strips another 30–50% at the Balanced preset.

Frequently asked questions
Everything you need to know about the PNG to JPG.
01Will PNG to JPG keep small text and UI lines sharp?
Not perfectly. JPEG at quality 92 is visually transparent for photographs but adds faint mosquito noise around one-pixel lines and small type, so interface screenshots, diagrams and anything with text are better kept as PNG or converted to WebP. Photos, product shots and scans are where the 3–10× size saving is free. Transparent pixels are composited onto white.
02What happens to transparency when converting PNG to JPG?
JPG has no alpha channel, so transparent regions must become a solid color — this converter flattens them onto white, the standard choice for documents, products and web use. If your image needs its transparency preserved, keep PNG or convert to WebP instead.
03Does the JPG keep the PNG's color profile and metadata?
No metadata survives: PNG text chunks, the embedded ICC profile and any EXIF are dropped, and the JPG is written as plain sRGB. If the PNG carried a Display P3 or Adobe RGB profile, the browser converts the colors to sRGB while decoding, so the JPG looks the same on a standard screen as the PNG did — but it will not be tagged for wide-gamut displays. Keep the PNG when color-managed output matters.
04Why convert PNG to JPG at all?
File size. Photographic PNGs are typically 3–10× larger than a visually identical JPG. For photos on websites, email and uploads, JPG at high quality is the right trade — reserve PNG for graphics needing sharp edges or transparency.
