PNG to JPG Converter
Our free PNG to JPG converter turns your PNG image into a smaller JPG file right in your browser. Upload a PNG, pick a quality level, and download the JPG — no upload to any server, no sign-up, and no watermark.
Your file stays on your device. It is converted in your browser and never uploaded anywhere.
How it works
When you pick a file, the page first checks that it really is a PNG. It looks at the file type your browser reports and at the .png ending on the file name. If you picked a JPG, a GIF, or a PDF by mistake, the tool stops and shows a friendly message instead of producing a broken download.
Next, the tool reads the PNG into your browser and draws it onto a hidden canvas. A canvas is a drawing surface that browsers use for images: the PNG is painted onto it pixel by pixel, and any transparent areas are filled with white first, because JPG has no way to store transparency.
Finally, the canvas exports the picture as a JPG at the quality you chose. Quality 1.0 keeps almost all the detail and makes the largest file, quality 0.9 is the sweet spot for most photos, and quality 0.7 throws away more detail to make a much smaller file. The result is offered as a download named after your original file, with the ending changed to .jpg.
Because every step happens on your computer, there is no waiting for an upload and no copy of your image sitting on someone else’s server. A large screenshot converts in a second or two, and you can convert as many files as you like, one at a time.
Worked example
Suppose you took a screenshot of a recipe on your phone and saved it as recipe.png. The PNG is 2.4 MB, which is too large to attach to an email, and the form you need to fill in only accepts JPG files under 1 MB.
Step 1: you click “Choose a PNG file” and pick recipe.png. The tool confirms it is a PNG and shows the file name.
Step 2: you leave the quality at 0.9 and click “Convert to JPG”. The tool draws the screenshot onto a canvas and exports it as a JPG.
Step 3: the result appears with a preview and a download button. The new file is called recipe.jpg and is about 620 KB — roughly a quarter of the original size — small enough to attach, and the text in the screenshot is still easy to read. You click “Download JPG” and the file lands in your Downloads folder.
If you needed it even smaller, you could run the same PNG through again at quality 0.7. The file would drop to around 350 KB, with slightly softer edges on the text — fine for a quick share, but not the best choice for a photo you plan to print.
When to convert PNG to JPG
Convert to JPG when file size matters more than pixel-perfect quality: email attachments, website photos, social media uploads, and forms with a size limit. A photo of a birthday party, a house, or a plate of food looks almost identical as a JPG at quality 0.9 and takes up far less space.
Stay with PNG when you need sharp lines or transparency: logos, icons, diagrams, screenshots of text you plan to zoom into, and any image with a see-through background. For those, JPG’s compression can blur fine edges and will turn transparent areas white.
One more tip: converting a JPG back to PNG will not restore the quality that was lost. Always keep your original PNG if you might need the best version later, and treat the JPG as a smaller copy for sharing.
FAQ
Is my PNG uploaded to a server?
No. Your image is drawn onto a canvas in your own browser and converted there. The file never leaves your device, so private photos and screenshots stay private.
Why is the JPG smaller than the PNG?
PNG uses lossless compression that keeps every pixel exactly, which makes large files. JPG uses lossy compression that throws away detail your eyes barely notice, so the same photo often shrinks by 50 to 80 percent.
What quality should I choose?
Use 1.0 for the best quality when file size does not matter, 0.9 for everyday photos and websites, and 0.7 when you need the smallest file for email or a form upload.
What happens to transparent parts of my PNG?
JPG does not support transparency, so any see-through area becomes white in the converted image. If you need to keep transparency, keep the file as a PNG instead.
Why does the converter reject my file?
This tool only converts PNG images. If you pick a JPG, GIF, PDF, or any other file type, it shows a friendly error and asks you to choose a PNG file ending in .png.
