Convert to JPG
Convert PNG, WebP, AVIF, HEIC, GIF, and BMP to JPG in your browser — control quality, batch process, and download instantly. No upload, no sign-up.
About this tool
Convert any image format to JPG without leaving your browser. Drop PNG, WebP, AVIF, HEIC, GIF, or BMP files, set the quality level you want, and download crisp JPGs — individually or as a ZIP. Everything runs client-side, so your images never touch a server.
How to use it
Quick steps to get the most out of this utility.
- 1
Drop your images
Drag and drop one or more images into the upload area, or paste from clipboard. Any format works.
- 2
Choose JPG quality
Use the slider (1–100%) or pick a preset: Low (30%), Medium (65%), or High (85%). Higher = larger file, sharper image.
- 3
Convert
Click "Convert to JPG" — each file is converted locally. HEIC files auto-load the decoder. A progress bar tracks batch status.
- 4
Download
Download each JPG individually or grab a single .zip of all converted files. Original filenames are preserved with .jpg extension.
Why convert images to JPG?
JPG remains the single most compatible image format on the planet. Every web browser, email client, social platform, and messaging app renders JPG natively. File sizes are dramatically smaller than PNG for photographic content, and smaller than WebP or AVIF for the broadest device support. If you need an image that “just works” everywhere — from a government form upload to a Craigslist listing to a slideshow — JPG is the safest choice.
As a concrete example: a 2.8 MB PNG screenshot from a design tool, converted to JPG at 85% quality, typically drops to 320 KB — an 89% reduction — with imperceptible quality loss for on-screen viewing. A 5 MB HEIC photo from an iPhone converts to roughly a 1.2 MB JPG at the same quality level, making it usable in every app that still rejects the HEIC format.
How the conversion works
This tool uses the browser's built-in Canvas API for standard formats (PNG, WebP, AVIF, GIF, BMP). The source image is loaded, drawn onto an HTML5 canvas, and re-encoded as JPEG at the quality level you specify. For HEIC files — Apple's default photo format — the tool lazy-loads the heic2any decoder only when a .heic or .heif file is detected, so regular conversions stay light and fast. The entire pipeline runs inside your browser's JavaScript runtime; no byte of your image touches a server.
A note on transparency: JPG does not support an alpha channel. If your PNG or WebP has transparent areas, they will be filled with a white background in the output JPG. If you need to keep transparency, use the Convert to PNG tool instead.
Why no-upload matters for image conversion
The images you convert often contain the most personal data on your device — family photos, ID documents, private screenshots, medical records, or financial statements. Upload-based converters send your original file to a remote server, where it may be stored, logged, or analyzed. You have no way to audit what happens after the upload. This tool processes everything locally: drag in a photo, hit Convert, and the resulting JPG streams directly to your download folder. No network request carries your pixels anywhere.

Frequently asked questions
Is this safe? Does it upload my image?+
No upload. The entire tool runs in your browser using JavaScript. Your image never leaves your device, never touches our server, and is never logged.
What image formats are supported?+
PNG, WebP, AVIF, HEIC, GIF, and BMP — all convert to JPG. You can mix formats in a single batch; each file is detected and converted independently.
What is the maximum file size?+
You can convert images up to ~50 MB each. Files over 25 MB will be slower, especially on mobile. For very large images, consider resizing first.
Will this work on mobile?+
Yes, on modern iOS Safari and Chrome for Android. Very large images (>25 MB) may be slow on older devices due to memory constraints. HEIC conversion is fully supported on mobile.
What happens to transparent areas in PNG or WebP?+
JPG does not support transparency. Any transparent areas (alpha channel) are filled with a white background. If you need to preserve transparency, use the Convert to PNG tool instead.
Why would I convert my images to JPG?+
JPG is the most widely supported image format — ideal for photos, web content, email attachments, and social media. Converting to JPG often dramatically reduces file size compared to PNG (up to 90% smaller for photographic content), and virtually every device and app can display it.
Can I convert multiple images at once?+
Yes. Drop or select as many files as you need and they are processed sequentially. Each output file gets a .jpg extension. After conversion, download each file individually or grab a single .zip containing all of them.
Does this support HEIC photos from my iPhone?+
Yes. HEIC/HEIF files (the default iPhone photo format since iOS 11) are detected automatically. The tool lazy-loads the HEIC decoder only when needed, so regular JPG/PNG conversions stay fast.
