How it works
- Drop your PNG files here, or select them from a folder.
- Each PNG is decoded and re-encoded as JPG in your browser.
- Lower the quality slider for a smaller file, or keep the default for best quality.
- Download the JPGs individually, or as one ZIP file.
A PNG screenshot straight from your phone or a design export from Photoshop is often five to ten times larger than it needs to be for sharing or uploading — most upload forms and email attachment limits are built around JPG (JPEG), not PNG. This tool re-encodes PNG to JPG entirely inside your browser: nothing is sent to a server, so there's no waiting on an upload and no privacy tradeoff for the smaller file. One thing worth knowing: JPG has no transparency, so any transparent background in the PNG is filled with white in the output. At the default quality, everything else looks the same to the eye.
Why use convert.pics?
- Smaller files: JPG typically shrinks a PNG considerably, especially photos and screenshots.
- No upload: conversion happens locally, so large PNGs never need to travel anywhere first.
- Works with any upload form or email client that rejects PNG or has a size limit.
- Batch conversion for a whole folder of screenshots or exports at once.
Frequently asked questions
Why did my transparent background turn white (or black)?
JPG has no transparency channel at all, so any transparent pixels in the PNG have to be filled with a solid color — this tool fills them white. If you need to keep transparency, keep the file as PNG or convert to WebP instead.
How much smaller will the JPG be than the PNG?
It depends heavily on the image, but for photos and screenshots, expect the JPG to be a fraction of the PNG's size — often a fifth or less. PNG is a lossless format built for flat graphics and screenshots with sharp edges, which is why it balloons in size on photographic content.
Does converting PNG to JPG lose quality?
Yes — JPG is a lossy format, so converting always re-encodes the pixels rather than copying them. At the default quality the loss is not visible to the eye, but it is real, which is why we don't advertise this as lossless.
How do I convert PNG to JPG without losing quality?
You can't eliminate the loss entirely — that's inherent to JPG — but raising the quality slider toward 100 minimizes it to the point of being imperceptible, at the cost of a larger file. The default setting (82) is a good balance for most images.
Can I convert a whole folder of PNGs at once?
Yes, drop in as many PNG files as you like and they'll convert in one batch, downloadable individually or as a single ZIP.
