PNG to JPG Converter
PNG is the right format for screenshots and graphics with see-through parts, and an expensive one for photos. Converting PNG to JPG typically shrinks a photo several times over and makes it acceptable to forms that ask for JPG.

85 keeps photos visually identical to the original. Lower it only when you need a smaller file.
JPG, BMP and EPS have no transparency. Transparent pixels are filled with this color.
Hex color used behind transparent pixels, e.g. #FFFFFF.
This format holds a single image. Choose GIF or WebP output if you want to keep the animation.
A multi-size icon contains several resolutions in one file; browsers and operating systems pick the one they need.
Keep the original dimensions, or enter one side and the aspect ratio is kept.
Pixels for the side you chose above.
Percentage of the original dimensions.
sRGB is right for screens and the web. Keep the original for print workflows; grayscale discards color.
Metadata only, 0 keeps the original value. Printers and some portals read this number; it does not change pixel dimensions.
How to use this tool
- 1
Upload your PNG files
Drag up to 20 PNGs into the box, choose them from a folder or paste a screenshot straight from the clipboard. Each file can be up to 95 MB.
- 2
Choose the fill for transparent areas
Transparent pixels become white unless you change Transparent areas under Advanced settings to black or a Custom colour such as your page background. Quality starts at 85.

How do I change PNG to JPG without a black background?
Upload the PNG, leave Transparent areas on white (or pick your own color), keep quality 85 and press Convert to JPG. Transparent pixels are filled with the color you chose instead of turning black.
Change PNG to JPG: what happens to transparency
A PNG can hold an alpha channel, a per-pixel opacity value from fully see-through to fully solid. JPG has nowhere to put that value, so a converter has to decide what color sits behind the image. Some tools pick black because transparent pixels are often stored as black with zero opacity; that is why a logo converted elsewhere sometimes comes back on a dark square. Here the fill is white unless you choose otherwise.
The fill matters most for logos and cut-outs with soft edges. A drop shadow or anti-aliased curve is partly transparent, and it blends into whatever color you set. If the JPG will sit on a light gray web page, enter that gray as a custom color and the edges disappear into it; leave white and you may see a faint outline. Fully opaque PNGs, which includes almost every photo and most screenshots, are unaffected.

When PNG to JPG makes sense, and when it does not
| Do | Don't |
|---|---|
| Convert photos that were exported or screenshotted as PNG before emailing them. | Convert a logo you still need on colored backgrounds; keep the PNG for that. |
| Convert when a form, marketplace or print lab lists JPG as the only option. | Convert UI screenshots full of small text unless you have to. |
| Set the fill color to match the background the image will appear on. | Delete the PNG master after converting. |
| Keep quality between 80 and 92 for photos you will print. | Expect converting to land under a specific KB cap by itself. |
PNG
Portable Network Graphics
PNG is a lossless raster format published in 1996 by the PNG Development Group and later standardised by the W3C and ISO. It keeps every pixel exactly, supports full alpha transparency and handles text, sharp edges and flat colours without artefacts. That precision makes it ideal for screenshots, logos, icons and interface graphics. The trade-off is size: photographs saved as PNG are often several times larger than the same photo as JPEG or WebP. All browsers, operating systems and editors open PNG files.

JPEG image
JPEG (or JPG) is the most widely used photo format, standardised by the Joint Photographic Experts Group in 1992. It uses lossy compression that discards fine detail the eye is unlikely to notice, which keeps photos small enough for the web, email and phone storage. It handles smooth gradients and natural scenes well, but sharp text, line art and flat colours pick up visible blocky or fuzzy artefacts. JPEG has no transparency and no animation, and every re-save loses a little more quality. Every browser, phone, camera and image editor can open it.

Converting PNG to JPG is about size and acceptance: photos saved as PNG are needlessly heavy for email and upload limits, and many forms and print services ask specifically for JPG.
Why so many photos end up as PNG
The screenshot tools on both major desktop systems save PNG by default: macOS with Shift-Command-3 or -4, and the Snipping Tool on Windows. Screenshot a photo or a video frame and you get a lossless file of something that never needed to be lossless. Design tools such as Canva and Figma also offer PNG as the default download in many cases, and phone editing apps sometimes export PNG to avoid compression.
JPEG was standardized in 1992 as ISO/IEC 10918-1 specifically for continuous-tone photographs, and it remains the format that cameras, phones and printers agree on. For a picture of people, places or products, it is the efficient choice; the JPG vs JPEG vs PNG guide goes deeper on when each one wins.
PNG to JPG questions
What happens to the transparent background when I change PNG to JPG?
JPG cannot store transparency, so every transparent or semi-transparent pixel is blended onto a solid color. White is the default; pick black or enter a hex code under Transparent areas to match the page or slide where the image will sit. Soft edges blend smoothly into that color rather than turning jagged.
How much smaller will my JPG be than the PNG?
For photographs, the JPG at quality 85 is commonly 70 to 90% smaller. For screenshots of text and interfaces the saving is smaller and sometimes nil, because PNG compresses large flat areas very efficiently while JPG spends bytes on every 8 × 8 block.
Why do letters look fuzzy in my converted screenshot?
JPG compression smooths sharp color transitions, so thin text picks up faint halos. Raise Quality to 95, or leave screenshots as PNG unless something forces JPG. Photos do not show this problem at normal viewing sizes.
Is there a way to hit an exact KB limit after converting?
Converting alone cannot target a size. Convert here first, then run the JPG through a size-targeted tool such as Compress image to 100 KB, which lowers quality step by step until the limit is met.
Can I convert PNG to JPG in Paint or Preview instead?
Yes: in Paint use File → Save as → JPEG picture, and in macOS Preview use File → Export and pick JPEG. Both handle one image at a time and fill transparency with white without asking. This page is quicker for a batch or when you need a different fill color.
Do I lose anything converting PNG to JPG?
You lose transparency and a little fine detail, which JPG trades for size. Keep the original PNG if you might edit the image again, and convert a copy; going back with JPG to PNG will not restore what was removed.
