Convert PNG to JPG Image Online
Convert PNG images to JPG online with adjustable quality, batch conversion, and ZIP download. Transparent areas are filled with the color you choose, and files never leave your browser.
How to Convert PNG to JPG Online
Upload one PNG or a whole folder, set the JPG quality, pick a background color for transparent areas, then download single files or a ZIP.
Step 1
Upload Your PNG
Step 1. Drop one PNG or drag in dozens at once — batch conversion is built in.
Step 2
Set Quality and Fill
Step 2. Choose a JPG quality level and the color used to fill transparent areas.
Step 3
Download JPG or ZIP
Step 3. Save each JPG separately, or grab the whole converted batch in one ZIP file.
Why Convert PNG to JPG in Your Browser Instead of Uploading
PNG and JPG were built for different jobs, and knowing which one you actually need saves a lot of frustration. PNG stores every pixel without throwing anything away, which is why screenshots stay crisp, logos keep sharp edges, and transparent backgrounds simply work. That lossless approach has a cost: a photograph exported as PNG can easily run five to ten times larger than the same picture saved as JPG. JPG takes the opposite trade. It discards colour detail the eye barely registers and keeps the result small, which is exactly what email attachments, upload forms, and web pages want.
Converting is therefore less about swapping a file extension and more about deciding how much detail you are willing to trade for size. This converter makes that decision explicit. A quality slider runs from 10 to 100 percent, so you can push a photo down to a few hundred kilobytes for a strict upload form, or hold it near 90 percent where the difference from the original PNG is invisible at normal viewing size. Because JPG cannot store transparency, any see-through pixels are painted with a background colour first — white by default, or any colour you pick. Nothing is guessed for you, and the PNG on your device is never modified.
The situations that bring people here tend to repeat. Government portals, visa applications, and exam systems frequently list JPG as the only accepted format and reject PNG outright. E-commerce listings and CMS image fields carry size caps that a heavy PNG screenshot will never clear. Photographers exporting finished work as PNG watch email clients bounce attachments over 25 MB. Developers compress design exports before pushing them to a staging site. Product teams shrink screenshots before pasting them into Slack or a support ticket. In each case the fix is the same: a smaller, universally readable JPG.
Doing this online usually means handing your files to somebody else’s server, which is awkward when the images are client assets, ID photos, or anything private. This tool does the encoding on your own device instead. Files are decoded and re-encoded through the browser canvas, so nothing is uploaded, no account is required, and nothing is kept after you close the tab. There is no watermark, no daily conversion quota, and no sign-up wall. Batch mode handles a whole folder at once, and when the job finishes you can download each JPG individually or pull the entire set down as one ZIP archive.
If your PNG is a logo or icon that needs to stay see-through, convert it to PNG or WEBP instead — JPG will always flatten it. For anything photographic, start at 85 to 92 percent quality, compare the sizes shown beside each result, and convert again if you need to go smaller. Keep the PNG as your master copy and treat the JPG as the version you share.
Batch Conversion
Drop in a whole folder of PNGs at once; each file is encoded and listed separately.
Adjustable Quality
Set JPG quality from 10 to 100 percent and watch the file size drop as you lower it.
Transparency Fill Color
Pick any background color for transparent PNG areas instead of being stuck with default white.
Max Width Resize
Cap the output width in pixels while converting, handy for clearing upload dimension limits.
Zero Uploads
All encoding runs locally through the Canvas API, so no image ever reaches a remote server.
One-Click ZIP
Download every converted JPG together as a single ZIP archive instead of saving them one by one.
FAQ
Frequently Asked Questions
Drop your PNG into the converter, choose JPG as the output format, adjust the quality slider if needed, then press convert. The JPG appears instantly and you can download it straight away — no sign-up, no email, and no file ever leaves your browser.
Yes, slightly — JPG is a lossy format. At 85 to 92 percent quality the difference is invisible for photographs at normal viewing size. You may notice softening around small text or flat graphics, so raise the slider to 95 or keep those images as PNG.
JPG cannot store transparency, so transparent pixels are filled with a solid colour before encoding. White is the default and suits most forms and ID uploads, but you can pick any colour from the background picker — useful when the image sits on a dark page.
Photographic PNGs usually shrink by 60 to 90 percent at 85 to 92 percent quality. Flat graphics, logos, and simple screenshots shrink far less, and can occasionally come out larger, because JPG handles large areas of solid colour poorly.
Yes. Drop in as many PNGs as you need and the converter processes them one by one, listing each result with its new file size. Download them individually, or use the Download All button to get the whole batch as a single ZIP file.
No. Decoding and encoding both happen inside your browser tab using the Canvas API, so your PNG files stay on your device. Nothing is uploaded, stored, or scanned, and there is no account to create — the page keeps working even without a connection.
Use 80 to 90 percent for photographs and general web images, and 90 or higher for screenshots containing small text, where compression artefacts show up first as faint noise around letters. Lower values are fine when you only need to clear a strict file size limit.
No. JPG wins for photographs and complex gradients, but PNG keeps sharper edges on text-heavy screenshots and supports transparency. If you want small files and transparency together, convert to WEBP instead — it keeps the alpha channel that JPG discards.
No. The image is re-encoded through the browser canvas, so camera model, capture date, and GPS coordinates are not carried into the new file. That is a privacy advantage when you plan to publish or share the picture publicly.
Yes. The converter runs in any modern browser — Chrome, Safari, Firefox, or Edge — on Windows, macOS, Android, and iPhone. There is no app to install and no desktop software to update; the same page works on every platform.
