WebP, AVIF & bulk image converter for Windows

The problem

Converting one WebP shouldn't be a gamble

A picture won't upload, so you search for a converter and land on upload queues, file caps, fake download buttons and installers you would rather not run.

Your pictures, on their server

Online converters want every picture sent to them first, then make you queue and download the results one by one.

Caps on size and count

Free tiers stop at a few files or a few megabytes, right when you drop the folder you actually needed converted.

Download buttons that aren't

Ad-covered pages where the big green button installs something else, and "free" converters that arrive with extras.

The .jpg that isn't a JPG

A WebP saved with a .jpg name still fails to upload, and renaming it never fixes it. Most tools don't even notice.

"Must be under 500 KB"

Upload forms set a size limit, and nudging a quality slider over and over is the only way most converters offer.

Animations frozen solid

Convert an animated WebP and many tools keep only the first frame, or quietly lose the timing between frames.

Vow Image Converter fixes all of it.

How it works

Drop. Check. Convert.

See the converted picture and its exact size first, then save it beside the original in one click.

  1. 01

    Drop your pictures

    Drag files or a whole folder onto the window, paste a picture copied in your browser, or click Recent downloads to grab the WebP and AVIF files you just saved.

Features

One converter for every picture on your PC

For anyone wrestling with upload forms, web downloads, phone photos or design files: two clicks for the basics, every option when you need it.

Opens 40+ picture formats

WebP, AVIF, HEIC, JPEG XL, PSD and PSB, SVG, TGA, QOI, every TIFF page, every ICO size and camera RAW such as CR2, NEF, ARW and DNG.

11 formats out

JPG, PNG, WebP, AVIF, JPEG XL, GIF, BMP, TIFF, ICO from 16 to 256 px, PDF (A4, Letter or picture size) and MP4 for animations.

See the result first

The Result tab shows the converted picture and its exact file size before you save, and looking costs nothing from your daily allowance.

Hits KB limits

Set "under 500 KB" and get the highest quality that fits, made smaller in pixels only when quality alone can't get there.

Catches fake extensions

Files are read by their real content, so a WebP named .jpg is flagged and turned into a genuine JPG that uploads.

Animations stay animated

GIF to animated WebP, WebP to GIF, or either to MP4 video, with every frame and its timing kept.

One-click recipes

Any picture to JPG, Under 500 KB, E-mail size, Transparent PNG, Fast website, Icon, Animation to GIF and Share privately.

True colours, upright photos

Display P3 and Adobe RGB become sRGB, photos are turned upright, and date, camera and place are kept or the location removed.

Convert from Explorer's menu

Convert with Vow to JPG, PNG, WebP or PDF straight from Explorer's menu, converted at once with Unlimited.

Auto-converts your Downloads

Watch Downloads or any folder: new WebP, AVIF, HEIC and JFIF pictures become JPG, PNG, WebP or PDF by themselves (Unlimited).

Light & dark theme

Easy on the eyes, day or night.

Image Converter comes with a crisp light theme and a calm dark theme. Switch with one click, or let it follow your Windows setting by itself. It remembers your choice.

Step-by-step guide

How to convert WebP to JPG (or anything else) on Windows

Turn a picture that won't open or upload into one that will, in under a minute, without sending it anywhere.

Step 1: get it free
  1. Install Vow Image Converter free

    Download it from this page and run the installer. It needs no administrator rights and no account, and it can add Convert with Vow to Explorer's right-click menu.

  2. Add the pictures

    Drag them onto the window, press Ctrl+O or paste with Ctrl+V, or click Recent downloads for the WebP, AVIF and HEIC pictures saved in the last 7 days.

  3. Choose the format

    JPG at quality 92 and full size is already picked. Click another format, a file size such as 500 KB, or a recipe like E-mail size.

  4. Look at the Result tab

    It shows the picture exactly as it will be saved, with its file size, before anything is written. Change the quality or size and look again.

  5. Press Convert

    Press Convert or Ctrl+S. The new file lands next to the original, which is never changed, and Ctrl+C copies the converted picture to paste anywhere.

FAQ

Questions about Image Converter

Is Vow Image Converter free?

Yes. You can convert 30 pictures a day, one at a time, for free, with every format and option, including size limits, resizing and the Result preview. There are no ads and no watermarks. Unlimited, a one-time $4.95 USD payment, adds whole-folder batches, Explorer's right-click convert and automatic conversion of your Downloads folder.

Are my pictures uploaded?

No. Every conversion happens on your own PC, and nothing is downloaded while it runs either: all the decoders are inside the installer. It works with no internet connection at all.

Why won't my .jpg upload?

Often it isn't a JPG at all: many websites serve WebP pictures that end up saved with a .jpg name, and upload forms reject them. Vow reads every file by its real content, flags the mismatch and turns it into a genuine JPG.

Can it make a picture smaller than 500 KB?

Yes. Pick a limit (200 KB, 500 KB, 1 MB, 2 MB or your own) and it finds the highest quality that fits, making the picture smaller in pixels only when quality alone isn't enough. It works for JPG, WebP, AVIF, PNG and PDF.

Which formats does it open?

More than 40, recognised by their content: WebP (still and animated), AVIF, HEIC and HEIF, JPEG and JFIF, PNG and APNG, GIF, BMP, TIFF, ICO and CUR, JPEG XL, SVG, PSD and PSB, TGA, QOI, JPEG XR, DDS and camera RAW such as CR2, CR3, NEF, ARW and DNG.

How is it different from XnConvert or online converters?

XnConvert reads a huge number of formats, but its interface is busy and it has no file-size targeting or fake-extension check. Online converters upload your pictures. Vow does the basic job in two clicks, shows the result and its size first, meets KB limits, spots fake .jpg files and never uploads anything.

Does it keep animations?

Yes. Animated WebP, GIF and JPEG XL stay animated when saved as GIF or animated WebP, with every frame and its timing, or become an MP4 video. You can also save just the first frame, or every frame as separate files.

Is it safe to install?

Yes. It is made and published by XTO Pty Ltd, an Australian company. The installer contains no ads, no toolbars and no bundled software, needs no administrator rights, never changes your default picture app, and uninstalls cleanly from Windows Settings.
