Convert PNG to JPG: what to know

PNG files are large because they are lossless. When a picture is a photograph, a rendered scene or anything without sharp text, JPG stores it in a fraction of the size with no visible difference. Converting is also the usual fix for upload forms that accept only .jpg. This page converts up to 20 PNG files to JPG at once, privately, with control over quality and transparency.

Transparency: decide what replaces it

JPG has no alpha channel. Any transparent pixels in the PNG have to become a solid colour, and the converter fills them with the background colour you choose — white by default, which suits most documents and web pages. Pick black, a brand colour or a colour matching the page the image will sit on. If you need the transparency to survive, convert to WebP instead.

Choosing a quality

The default of 85 keeps a photo visually identical to the PNG at typically 5–10× smaller. For web use, 75–80 saves a little more with no noticeable change on most screens. Below 60, smooth gradients start to band and edges gain faint halos; use those values only when a strict size limit forces it, or better, send the result to the compressor and let it find the quality that fits a target such as 200 KB.

When you should not convert PNG to JPG

Screenshots with text, diagrams, logos and pixel art look worse as JPG: the lossy encoder blurs sharp edges and introduces colour noise around letters. Keep those as PNG, or try WebP, which handles flat graphics far better than JPG at a similar size.

Images you will keep editing should also stay PNG. Every time a JPG is opened, changed and saved at a lossy quality, a little more detail is lost.

What the converter does

The PNG is decoded, transparent areas are filled, and the pixels are encoded with MozJPEG — the same encoder used by the compressor — which produces smaller files than a browser's built-in JPEG writer. Metadata is not carried over. Each result row shows the before and after size; download files one by one or as a ZIP.

Questions about PNG to JPG

My PNG has a transparent background — what will the JPG show?
The background colour you pick, white by default.
Which quality should I use?
85 for general use, 75–80 for web pages, or use the compressor's Target size for an exact limit.
Will text screenshots look OK as JPG?
Rarely. Keep PNG or use WebP for anything with sharp text or lines.

How to convert an image to another format

  1. Add up to 20 images — JPG, PNG, WebP, HEIC, AVIF, GIF, BMP, SVG, ICO or TIFF. They stay in your browser.
  2. Choose Convert to: JPG for photos you will share anywhere, PNG for graphics with transparency, WebP or AVIF for the smallest files on the web.
  3. Click Convert, check the size next to each file, then Download one by one or as a ZIP — or send the results to the compressor or cropper.

Quality applies to JPG, WebP and AVIF. PNG is always lossless. If a transparent image is converted to JPG, the transparent areas are filled with the background colour you choose.

Useful details

Are my images uploaded?

No. Conversion runs in your browser using built-in codecs; the files are never sent to Toolkitta. Keep the tab open until you download or send your results — reloading clears the batch. Website hosting and performance measurement are described in our Privacy notice.

Which formats can I convert from and to?

In: JPG, PNG, WebP, HEIC/HEIF (iPhone photos), AVIF, GIF, BMP, SVG, ICO and TIFF, up to 20 files, 20 MB each and 100 MB per batch, at most 40 megapixels. Out: JPG, PNG, WebP and AVIF. Animated GIF, WebP and PNG keep their first frame only.

Why does my iPhone photo have no file type on Windows?

Some systems do not recognise HEIC and leave the type blank. The converter identifies files from their contents, so a .HEIC file with no type still opens; HEIC decoding is downloaded once (about 2 MB) the first time you add one.

What happens to transparency?

PNG, WebP and AVIF keep it by default; untick Keep transparency to flatten onto a background. JPG cannot store transparency, so transparent areas are filled with the background colour (white by default).

Is metadata (EXIF, location) kept?

No. Every converted file is rebuilt from pixels, so camera settings, GPS location and other embedded metadata are removed. Orientation is applied to the pixels first, so photos are not rotated. Keep your original if you need the metadata.

Which quality should I choose?

Start at the defaults (JPG 85, WebP 80, AVIF 60). For photos on the web, 70–80 is usually indistinguishable. For an exact kilobyte target, send the result to the compressor and use Target size.

Is AVIF safe to use?

All current browsers and phones open AVIF and it produces the smallest files, but some older desktop software, email clients and upload forms reject it. Use WebP or JPG when you are not sure what will open the file.

How do I continue in another tool?

Use Send to beside a converted image, or Send all to for the batch, to open the compressor, cropper or Image to PDF tool with those results already loaded. Every session stays available until you reload the page.

Can I convert images to PDF here?

Not in this tool — PDF is a document, not an image format. Convert first if you need a specific format, then use Send to → Image to PDF, or open the Image to PDF tool directly to combine JPG, PNG, HEIC or WebP files into one PDF with page size and order controls.
