Image Converter
Switch an image to PNG, JPG, WebP or AVIF in a couple of clicks, with a quality slider and proper control over transparency. It opens HEIC, GIF, BMP and SVG files too, and it all runs in your browser, so conversions are instant and your files stay on your machine.

How to convert a photo
- 1
Open your image
Drag a photo onto the editor, paste one from your clipboard, or click to browse for a file. It loads on the spot, and nothing is sent over the network.
- 2
Pick an output format
Select PNG, JPG, WebP or AVIF. Reach for PNG when you need transparency or crisp lines, JPG for small photos, and WebP or AVIF for lean web files.
- 3
Adjust the quality slider
For JPG, WebP and AVIF, drag the quality slider while watching the preview. Lower settings make smaller files; stop where the image still looks right to you.
- 4
Set the background for transparency
Converting a transparent image to JPG? Choose a background fill color first, since JPG has nowhere to store the see-through pixels.

Download the result
Export in your chosen format and the file saves straight to your device. No sign-up, no watermark, no limit on how many you convert.
Why use PicStudio for this?
The need usually shows up out of nowhere. An upload form rejects your PNG and demands JPG. A page you're building loads slowly, and switching the hero image to WebP or AVIF would shave off most of the weight. Your iPhone hands you a HEIC that a form won't take, or someone emails an AVIF your old photo app won't open. Rather than installing a desktop app or handing your files to a site you've never heard of, you drop the image here, choose the output format, and save it. Each format earns its place: PNG holds sharp edges and transparency, JPG keeps photographs light, WebP hits a strong size-to-quality ratio for the web, and AVIF goes smaller still where the browser supports it.
Convert between PNG, JPG, WebP and AVIF.
Nothing you open here is sent anywhere. There's no upload bar to wait on and no copy sitting on a server afterward, because the conversion is done by your own browser on your own device. That also means it costs nothing, needs no account, and never stamps a watermark on the result. On a phone you can fix one stubborn photo; on a desktop, Batch mode churns through a whole folder — drop in many files at once, watch per-file progress, and download the results individually or as a single ZIP.
Two things are worth knowing before you export. Formats like JPG have no concept of transparency, so when you convert a transparent image the see-through areas get painted with a background color you pick; if transparency has to survive, stay on PNG or WebP. The quality slider is where the real savings live for JPG, WebP and AVIF. Pushing it down a little often cuts the file size in half with nothing your eye can catch, so nudge it while watching the preview rather than guessing. For photos bound for the web, WebP and AVIF tend to land smaller than JPG at the same visual quality.
After you settle on format and quality, hit download and the file lands in your device's downloads folder. If shrinking the file matters more than changing its type, run it through the compressor for tighter size control afterward, or resize it first when the dimensions are bigger than the layout actually calls for.

Frequently asked questions
Is the image converter free to use?
Yes. It's free with no account, no watermark on the output, and no cap on how many images you convert.
Are my images uploaded to a server?
No. The conversion happens in your browser on your own device, so the files never get uploaded. That's what keeps it both instant and private.
Which formats can I convert between?
You can open JPG, PNG, WebP, AVIF, GIF (first frame), HEIC, BMP and SVG, and export to PNG, JPG, WebP or AVIF. That covers common jobs like PNG to JPG, HEIC to JPG and SVG to PNG.
Can I convert many files at once?
Yes. Batch mode takes as many files as you drop in, converts them one at a time on your device with per-file progress, and lets you download each result or everything as one ZIP.
What happens to animated GIFs?
The converter keeps the first frame and exports it as a still image — animation isn't preserved. SVG files are rasterized crisply at roughly twice their declared size.
What happens to transparency when I convert to JPG?
JPG can't store transparency, so the see-through areas are filled with a background color you choose. To keep transparency, export to PNG or WebP instead.
Will converting reduce my image quality?
PNG conversion is lossless. For JPG, WebP and AVIF you set the quality slider yourself: high settings stay visually identical, lower ones trade a bit of detail for a much smaller file.
Which format gives the smallest file for the web?
AVIF usually produces the smallest file at a given quality, with WebP close behind and supported in more browsers. Both generally beat JPG at the same visual quality.
Does the converter work on my phone?
Yes. The interface adapts to the screen, so it works the same on phones, tablets, laptops and large monitors.
