How to convert PNG to JPG
Drag a PNG into the box — it opens locally and is never uploaded. If your PNG has transparent areas, pick a fill color for them; white works for most cases, black works on dark backgrounds.
Set the quality — 90 is a good default for photos and screenshots; lower it only if you need an especially small file. Then click Convert & Download.
The size readout shows your PNG next to the JPG — the JPG is typically five to ten times smaller, which is the whole point. Save the result and keep your original PNG somewhere safe if you might need the lossless version again.
Know-how
When the PNG is overkill
PNG earned its reputation for crispness, but crispness has a price: a photo saved as PNG can be ten times the size of the same photo as JPG. If the image is going into a chat, a social post, an email, or a website, that extra weight buys nothing — the viewer sees the same picture. PNG is the right choice for graphics and screenshots with text; for photographs heading somewhere public, it is simply the wrong tool, and converting to JPG is the fix.
The transparency trap
Every PNG-to-JPG conversion must answer one question: what fills the transparent areas? JPG simply has no alpha channel. Most converters silently pick white — which looks broken the moment the image lands on a dark background or in dark mode. That is why this tool lets you choose the fill before converting: white for documents, black for dark interfaces, or any brand color that matches your destination. If the transparency itself matters, keep it as PNG.
Screenshots: the classic case
Screenshots sit exactly on the PNG-JPG fault line. They contain text, so PNG keeps them razor-sharp; but they also travel constantly — into tickets, chats, and reports — where a multi-megabyte PNG is a nuisance. The practical rule: capture and edit in PNG, then convert the final to JPG at quality 90 when you send it anywhere. You keep the sharpness where it matters, and the size drops by an order of magnitude.
Quality 90: the sweet spot
JPG quality runs from 0 to 100, but the useful range is narrow. Below 80, artifacts appear — fuzzy edges around text, color banding in skies. Above 95, the file balloons with no visible gain. Between 85 and 92 is where the eye stops noticing, which is why 90 is the default here. Only drop below 85 when a platform demands a hard size limit, and never go back to edit a low-quality JPG — start over from the PNG.
Keep the PNG as the master
The cleanest workflow treats the PNG as the master and the JPG as a disposable copy. Every edit happens on the PNG — crops, text, color changes — because it loses nothing on each save. Only the final export becomes JPG, sized for its destination. If you ever need a different size, quality, or background fill, you do not re-compress an old JPG (that stacks artifacts); you re-export from the master. One master, many exports — that is the professional habit.
Frequently asked questions
Is the PNG to JPG converter free?+
Yes. Conversion runs entirely in your browser — there is no server, no upload, and no limit on how many files you convert.
What happens to transparent areas?+
JPG has no transparency, so those areas are filled with the color you pick — white by default. Choose the fill that matches where the image will be used: white for documents and light backgrounds, black for dark-mode apps or dark slides.
Does converting to JPG lose quality?+
Yes — that is the trade. JPG compresses with loss to reach its small size. At quality 90 the difference is invisible in almost every photo and screenshot. Keep the original PNG if you might need a lossless version later; use the JPG for sharing and uploading.
Why is the JPG so much smaller?+
Because the two formats save pixels differently. PNG writes every pixel exactly, which is expensive. JPG groups similar colors and approximates — your eye rarely notices, but the file shrinks dramatically. A photo PNG is usually five to ten times its JPG twin, sometimes more.
Which should I keep — the PNG or the JPG?+
For finished photos you will share or upload, keep the JPG — it is far smaller and looks the same. Keep the PNG as your archive copy when the image is a graphic with text, a screenshot you may edit again, or anything you created and might want to re-edit losslessly.
