How to convert PNG to JPG
- Drop your PNG files onto the box above, click to browse, or paste a screenshot straight from your clipboard.
- Set the JPG quality slider, 90% keeps screenshots and photos looking crisp while cutting most of the weight.
- Preview each result, then download JPGs one at a time or hit Download all to grab the whole batch.
Why convert PNG to JPG?
PNG is a lossless format: it records every pixel exactly, which is fantastic for editing but brutal on file size. A full-screen screenshot or a photo exported as PNG routinely weighs 3-8 MB. Re-encoding it as JPG applies lossy compression tuned for continuous-tone imagery, and the same picture usually drops to somewhere between 200 KB and 800 KB, commonly a 70-90% saving.
That size difference is the whole point. Email providers reject oversized attachments, job portals cap uploads at 2 MB, marketplace listings choke on heavy photos, and web pages built from PNG photos crawl on mobile data. JPG is the format that sails through all of them, which is why it has been the default for sharing photographs for three decades.
Two things change in the swap. First, transparency disappears, JPG has no alpha channel, so anything transparent is painted onto a white background as the file is saved. Second, the compression is permanent, so this is a step you take when you are ready to share the image, not while you are still editing it.
When to keep the PNG instead
JPG is not always the right answer. Reach for it when the image is photographic and headed out the door; keep the original PNG when any of these apply:
- Screenshots full of small text or UI: JPG compresses in 8x8 blocks, so razor-thin edges can gain faint halos. PNG keeps them pin-sharp.
- Logos, icons and line art: flat colours and hard borders stay cleaner as PNG, and you keep the transparent background.
- Images you will edit again: every JPG save discards a little more detail, so work in PNG and export to JPG only at the end.
Need the small size and transparency? Convert to WebP instead, it compresses like JPG but keeps the alpha channel intact.
Frequently asked questions
Why convert PNG to JPG?
PNG saves every pixel losslessly, so a full-screen screenshot or a photo exported as PNG can easily run 3-8 MB. JPG re-encodes the same image with lossy compression and usually lands between 200 KB and 800 KB, often a 70-90% reduction. That makes it the practical choice for email attachments, marketplace and forum uploads, job-application portals with a 2 MB cap, and anywhere a lighter file simply moves faster.
What happens to transparent areas?
JPG has no alpha channel, so transparent pixels are flattened onto a solid white background as the file is written. If your PNG is a logo or sticker that needs to stay see-through, convert it to WebP instead, which keeps the transparency.
Will the text in my screenshots stay readable?
Keep the quality slider at 90% or higher and it stays sharp for almost everything. JPG works in 8x8 pixel blocks, so very fine text and hard UI edges can pick up faint halos at low quality. For a screenshot that is mostly small text, PNG or WebP preserves those edges more faithfully.
What quality setting should I choose?
The slider runs from 50% to 100%. 90% is the sweet spot for photos and screenshots, visually indistinguishable from the source at a fraction of the size. Drop toward 70-75% when you need the smallest possible file and the image is a photo without fine text, and reserve 100% for images you plan to edit again.
Can I convert a whole folder of PNGs at once?
Yes. Drop or paste as many PNGs as you like and they convert together in your browser; the Download all button saves the finished JPGs in one go. Because the work happens on your own device, there is no file-count or size limit beyond your computer's memory.
Is anything uploaded?
No. The conversion uses your browser's built-in Canvas engine, so every PNG is decoded and re-encoded locally. Nothing is sent to a server, exactly what you want for screenshots that contain personal or work information.
