Photos and uploads
JPG makes small, compatible files. Great for photos, email, forms, and social posts. It uses lossy compression and cannot keep transparency.

The no-nonsense format guide
Pick the format that fits the job.
Logos and transparency
PNG keeps every pixel and supports transparent backgrounds. It is crisp, but photo files can get much larger.
Websites and lighter files
WebP can keep transparency while usually weighing less than PNG or JPG. It is a strong default for modern websites.
A quick heads-up from the guy making this:
Changing a file format cannot restore detail that was already lost. PNG is lossless, while JPG and WebP use the quality setting. An animated GIF becomes one still image—the first frame—because this tool is for image conversion, not animation editing.
Fast on purpose
Three stops. No scenic route.
Pick a format
Choose JPG, PNG, or WebP. The defaults are already good.
Add a batch
Drop in one image or up to 25. They stay on your device.
Save the results
Download one file or grab the whole batch as a ZIP.
Good questions, straight answers
Before you convert.
Does image conversion reduce quality?
It depends on the output. PNG is lossless. JPG and WebP can lose a little detail because they compress the image; 90% is a solid everyday setting. Repeatedly converting a JPG can add more artifacts, so keep the original when it matters.
Which input and output formats are supported?
You can add JPG, PNG, WebP, HEIC/HEIF, AVIF, and GIF files. The tool exports JPG, PNG, or WebP. Animated GIFs export as a still image using the first frame. AVIF decoding depends on browser support.
Can I convert iPhone HEIC photos to JPG?
Yes. HEIC and HEIF decoding happens locally using code bundled with this page. Large iPhone photos can take a moment on older phones, but they are never uploaded.
Is this an AI tool? Are my images uploaded anywhere?
No and no. This is a hand-coded browser utility, not an AI service. Your browser reads the files and creates the new copies on your device. There is no image-upload endpoint, and HandyPebble cannot inspect your photos.
What happens to transparency?
PNG and WebP can keep transparent pixels. JPG cannot, so the tool replaces them with the white, black, or warm background you choose.
Why did the converted file get larger?
Conversion changes the container, not just the extension. A photo converted from JPG to lossless PNG often gets much larger. If a smaller file is the goal, use JPG or WebP—or try the Image Compressor.
What happens to EXIF and GPS metadata?
The new canvas-made file normally drops embedded camera and location metadata. That can improve privacy, but keep the original if you need shooting details or color-profile data.
Does it work on phones?
Yes. You can choose images from your photo library and download the converted results. For huge HEIC batches, a laptop may be faster because all work happens on your device.
