How it works
- 1
Drop your images
Drag and drop multiple PNG, WebP, GIF, or BMP files onto the tool, or click to browse and select them.
- 2
Choose quality
Pick High, Medium, or Web quality. The images are converted instantly and the result updates live.
- 3
Download
Download individual JPGs by hovering over them, or grab all images in one ZIP archive.
Why use this image converter?
100% private
Images never leave your device. Everything runs locally in the browser — no server upload, ever.
Instant, no sign-up
No account or email needed. Drop images and get JPGs in under a second.
Quality control
Choose from three quality presets — High, Medium, or Web — and switch instantly to compare results.
Batch conversion
Convert many images in one go. Drop as many files as you need, all processed simultaneously.
Size comparison
Each converted image shows the original size vs JPG size — and the percentage reduction — at a glance.
Individual or ZIP download
Download a single JPG with a hover click, or grab everything as a named ZIP archive.
When would you convert PNG to JPG?
PNG and JPG serve different purposes. Knowing when to switch can dramatically reduce file sizes.
Reduce web page load time
PNG files are significantly larger than JPG for photographic images. Converting hero images, blog photos, and product shots from PNG to JPG can cut file sizes by 50–80%, improving page load speed and Core Web Vitals scores.
Send smaller email attachments
Email clients have attachment size limits. Converting PNG screenshots, diagrams, or photos to JPG before attaching them keeps emails within limits and loads faster for recipients.
Reduce storage on mobile
Screenshots and app-generated images are often saved as PNG. Converting them to JPG frees up significant storage space on phones and tablets without noticeable visual quality loss.
Prepare images for print
Many print services accept JPG but not PNG or WebP. Convert your images before uploading to online print shops, poster services, or marketing platforms.
Upload to social media and CMS
Platforms like WordPress, Shopify, and social networks have file size upload limits. JPG files are typically far smaller than PNG, making uploads faster and less likely to hit size restrictions.
Convert design exports
Design tools like Figma and Sketch export assets as PNG by default. If you need JPG for a specific platform or size requirement, convert them here in bulk rather than re-exporting from your design tool.
How PNG-to-JPG conversion works under the hood
No servers, no uploads — here is exactly what happens when you convert an image in your browser.
- 01
Images are read locally
When you drop files onto the tool, the browser reads each image directly from disk using the File API. No data is sent over the network at any point — everything stays on your device.
- 02
Each image is loaded into an HTML5 canvas
The browser creates a hidden canvas element sized to match the image's exact pixel dimensions. The image is decoded and drawn onto the canvas — this step uses your device's hardware-accelerated graphics pipeline, making it very fast.
- 03
Transparent pixels are filled with white
JPG has no alpha channel, so transparency is not supported. Before drawing the image, the canvas is filled with white. Any transparent areas in PNG or WebP images become white in the output JPG.
- 04
The canvas is exported as JPEG
The browser's built-in Canvas API encodes the canvas as a JPEG image at the quality level you selected (95%, 85%, or 72%). The encoding uses the browser's native JPEG encoder, which is optimised for speed.
- 05
The result is available instantly
The encoded JPEG is returned as a data URL in memory. For single files it is immediately downloadable; for multiple files, JSZip bundles them into a ZIP archive in the browser before download.
PNG vs JPG — understanding the difference
Choosing the right format for the job can cut file sizes dramatically. Here is how PNG and JPG compare across the most important dimensions.
| PNG | JPG | |
|---|---|---|
| Compression | Lossless — pixel-perfect | Lossy — some detail discarded |
| Transparency | Supported (alpha channel) | Not supported |
| File size | Large for photos, small for UI | Smaller for photos (50–80%) |
| Photo quality | Perfect but very large files | Excellent at 85%+, imperceptible loss |
| Best for | Screenshots, logos, diagrams, UI | Photographs, web images, sharing |
| Browser support | Universal | Universal |
Tips for the best JPG output
Getting the best results from PNG-to-JPG conversion comes down to a few simple practices.
Use "High" quality for professional photos
For product photography, portfolio images, or any photo destined for print, use the High (95%) setting. The JPG quality is indistinguishable from the original PNG, with a fraction of the file size.
Use "Web" quality for website images
For blog images, hero images, and web assets where fast load time matters more than pixel-perfect quality, the Web (72%) preset produces files that are significantly smaller and still look great on most screens.
Keep PNG for text and logos
JPG compression introduces subtle artefacts around sharp edges — most visible on text, icons, and logos. If your image contains fine text or line art, keep it as PNG. Only convert photographs and photographic backgrounds to JPG.
Check transparent areas beforehand
If your PNG has a transparent background (e.g. a logo or a product shot with cutout), the transparent area will become white in the JPG. If you need a different background colour, edit the PNG in an image editor before converting here.
