Change a PNG into a JPG
Drop your PNG files here or tap the button to pick them. A whole batch works in one go.
Choose a preset or drag the quality slider, then decide which colour replaces see-through parts and whether to scale the picture down.
Hit Convert and save the JPEG files one by one or bundled in a single ZIP archive.
Built for the jobs where file size matters
Hit the size limit on the first try
Every preset is labelled with the size it produces on your own picture, and the slider updates a measured figure as you drag it. Several files at once? You get an estimated total for the whole set.
Logos and cut-outs on any backdrop
Since JPEG has no see-through layer, the tool puts a solid colour behind your picture: white, black or an exact shade from the colour picker. Anti-aliased outlines and drop shadows melt into it cleanly.
Fewer pixels in the same pass
Cap the longest side from 4K down to 800 px, scale to 75, 50 or 25 percent, or type a maximum width and height. Pictures are never upscaled, and a split view with a 100% zoom lets you inspect fine detail.
Print size and file names sorted
A DPI value stored in the PNG is carried over, so a 300 DPI scan still prints at its real size. Pick .jpeg or .jpg as the extension, and duplicate names inside the ZIP are numbered for you.
Who needs PNG to JPEG, and which settings to use
Design apps, phone screenshots and many exports save pictures as PNG by default. That is great for sharp graphics, yet a photo stored this way can weigh several megabytes, which is too much for a job portal, a listing site or a crowded inbox. Switching it to JPEG is the quickest fix. Here is how different people set up the toolbox for their task.
Typical jobs
- HR and job seekers: a portrait or certificate saved as PNG can be rejected by an application form with a small cap. The Small preset plus a 1024 px longest side keeps it light.
- Real estate agents: room photos edited and exported as PNG upload slowly. Balanced quality with Full HD dimensions keeps them crisp on listing pages.
- Freelancers and online shops: a product cut-out needs to match the shop theme. Enter the theme colour in Custom so the edges blend in.
- Teachers and students: scanned worksheets keep the print resolution stored in the PNG, so printed copies come out at the original paper size. Choose Maximum for small handwriting.
Worth checking before you convert
- A plus sign next to the measured size means the JPEG is heavier than the PNG. That often happens with charts and screenshots, so leave those files as they are.
- An animated PNG becomes a still JPEG built from its opening frame.
- On a phone, a very large image may need a Resize option because the work happens in device memory.
- Files that cannot be read do not stop the batch: they are skipped and named at the end.

Questions people ask about this task
How do I change a PNG into a JPEG without installing anything?
Open this page in any modern browser on a phone, tablet or computer and select your PNG files. Pick a quality, press Convert and save the finished JPEG files from the result screen.
Is JPEG the same thing as JPG?
Yes, they are one and the same format; only the length of the extension differs. Files are named .jpg by default, and you can switch to .jpeg under More options if a system expects that ending.
How can I get a PNG under an upload size limit?
Start with the Balanced or Small preset and check the measured size next to it. If the file is still too heavy, set Resize to a longest side of 1280 px or 50% and the size drops sharply.
My PNG has a transparent background. What colour will the JPEG get?
White, unless you choose otherwise. Switch to black, or tap Custom and pick any shade so the picture sits naturally on a coloured slide, flyer or web page.
Should I turn screenshots and logos into JPEG?
Often not. Flat colours and crisp text usually stay smaller and sharper as PNG, and the preview flags it whenever the JPEG would come out larger than the original.
Do my pictures get sent to a server?
No. The whole job runs inside your browser tab, so the files stay on your own device. Text notes stored inside a PNG are left out of the JPEG.
