Stops further quality loss
Every time a JPG is edited and saved again it loses a little more. As a PNG it can be opened and saved as often as you like without degrading.

Every pixel of the JPG, stored exactly, as a PNG. There is nothing to configure: PNG has no quality setting and JPG has no transparency to preserve. The files will be bigger — that is the price of keeping every detail. Nothing leaves your browser.
A copy that won't lose more quality as you edit, or the format an uploader insists on.
Every time a JPG is edited and saved again it loses a little more. As a PNG it can be opened and saved as often as you like without degrading.
Screenshots, diagrams and lettering keep their hard edges as PNG instead of picking up halos from repeated JPG saves.
Some sites and design tools only accept PNG. Convert once and upload, without re-exporting from an editor.
Keeping every detail makes files larger — often five to ten times. The panel warns before you start and the result screen shows the exact sizes.
A JPG has no transparent areas to carry over. If you need the background gone, Remove Background returns a transparent PNG.
Turn a set of JPGs into PNGs in a single run and download them together.
| You need | Use | Why |
|---|---|---|
| To keep editing the file | PNG | Each JPG save loses a little more; PNG does not |
| Hard edges and text | PNG | JPG smears sharp contrast into halos |
| A site or tool that demands PNG | PNG | Some uploaders only accept it |
| A photo that will only be viewed | JPG | A tenth of the size, no visible difference |
| Transparency | Neither, from here | A JPG has none to keep — use the background remover |
Converting stops the damage; it does not undo it. Here is where each half of that is written down.
PNG keeps a picture exactly as it is. Once your JPG is a PNG, you can open, edit and save it as often as you like and it will not get any worse. That is the whole point of this conversion.
“This document describes PNG (Portable Network Graphics), an extensible file format for the lossless, portable, well-compressed storage of static and animated raster images.”When a photo is saved as a JPG, some detail is thrown away for good. Converting it to PNG keeps everything that is left but cannot bring back what is missing, so the PNG looks exactly like the JPG you put in.
“In effect, JPEG tries to throw away details we weren't likely to see in the first place, so it can sneak additional compression past us.”The damage shows most around text and sharp edges, which is why screenshots, diagrams and lettering are the pictures where the bigger PNG file is worth it.
“For screenshots, diagrams, logos, and line art, prefer lossless encoding, as blurring and colored fringes around text and sharp edges are very visible.”Six uploads that turn a JPG away, the rule behind each one, and how to get the PNG they want. Every rule links to the platform's own documentation.
The Chrome Web Store requires a 128 × 128 px extension icon and says the image must be in PNG format. It also notes that an icon without transparent areas is placed in a frame with rounded corners.
How it helps
Convert the JPG here, then choose Resize these PNGs and set 128 × 128. A JPG has no transparency to carry over, so expect the rounded frame, or use Remove Background to get a transparent PNG instead.
A Microsoft Teams app package must include two PNG versions of the app icon, and the colour icon must be 192 × 192 px. A company logo that only exists as a JPG can't go into the package as it is.
How it helps
Convert the logo to PNG, then choose Resize these PNGs and set 192 × 192. Teams asks for a square filled edge to edge and rounds the corners itself, so the JPG's solid background can stay as it is.
Canvas Credentials, the badge service of the Canvas learning platform, lists PNG and SVG as the file formats for badge images, recommends 400 × 400 px for a PNG, and tries to resize larger PNGs to that size. Badge artwork delivered as JPG isn't one of the two.
How it helps
Convert the whole badge set, up to 30 at a time, and download one ZIP. Instructure notes badges usually appear on a white background, so check how a JPG's background looks on darker job profiles too.
Discord's requirements for a static custom sticker are a PNG file, a maximum of 512 KB and dimensions of exactly 320 × 320 px. Community art saved as JPG doesn't meet the file type, whatever its size.
How it helps
Convert here, then Resize these PNGs to 320 × 320 and read the size on each card. If one is over 512 KB, Compress them uses fewer colours and keeps it a PNG. Transparency isn't on Discord's list of requirements.
Telegram stickers must be .PNG or .WEBP files with one side exactly 512 px and the other 512 px or less, and custom emoji must be exactly 100 × 100 px. Artwork finished as JPG has to be converted first.
How it helps
Convert the set to PNG in one run, then Resize these PNGs to 512 px on the long side. Telegram suggests a transparent background; a JPG has none, so art drawn on a colour keeps that colour.
Microsoft Store screenshots must each be a .png file no larger than 50 MB, at least 1366 × 768 px for desktop, and a trailer thumbnail must be a 1920 × 1080 PNG. Captures saved as JPG don't qualify.
How it helps
Drop in up to 30 captures and download the PNGs in one ZIP. Pixel dimensions are kept, so a 1920 × 1080 still stays 1920 × 1080. PNG keeps every detail and is larger, so check each card's size against 50 MB.
PNG stores every pixel exactly, while a JPG keeps a close approximation. Five to ten times larger is normal and means nothing went wrong.
No. What a JPG threw away is gone; the PNG preserves exactly what the JPG contains, from here on, without losing any more.
When the image will be edited again, when it has hard edges and text (screenshots, diagrams), or when a site or tool demands PNG. For photos that are only going to be viewed, JPG is the better format.
Not from this tool — a JPG has no transparency to preserve. Use the background remover to cut the subject out onto a transparent PNG.
No. The conversion runs in your browser.
