Frequently asked questions
Is this image converter free?
Yes. verto is free to use, no account is required, and there are no paid plans.
Are my images uploaded to a server?
No. verto runs entirely in your browser. Your images are never uploaded, never seen by our infrastructure, and never stored anywhere outside your device. When you close the tab, every file is gone.
Which formats are supported?
Inputs: JPG, PNG, WebP, AVIF and GIF (first frame). Outputs: JPG, PNG, WebP and AVIF. TIFF, SVG, HEIC, RAW, PSD, AI, EPS and PDF are not supported in this version.
Can I convert images to WebP?
Yes. WebP is one of the recommended output formats and is supported in the browser on all modern devices.
Can I convert images to AVIF?
Yes, if your browser supports AVIF encoding. Most up-to-date Firefox and Chromium-based browsers do; if your browser refuses, you'll see a clear error and you can pick another format.
Why is HEIC not supported?
HEIC needs a separate, licensed codec that is not yet practical to run in the browser. Until that changes, please export HEIC images to JPG or PNG first.
Does JPG support transparency?
No. JPG cannot store transparent pixels. When you convert a transparent image to JPG, verto fills the transparent areas with white and shows a warning on the file row.
Can I convert multiple images at once?
Yes. You can convert up to 50 images in a single batch and download them individually or as a single ZIP.
Is there a file size limit?
Yes. Each file may be up to 20 MB. There's no daily or hourly cap because nothing runs on a server — your device is doing the work.
Are ads required to use the tool?
No. Ads are isolated from the converter. The tool works completely even if ads fail to load or are blocked.
