ImageConv
Chrome & Edge extension

Local image format conversion in your browser

PNG/JPG/WEBP/AVIFFully Private

ImageConv is an image converter for Chrome and Edge that turns pictures into PNG, JPG, WebP or AVIF without sending them anywhere. Right-click any image on a page and save it in the format you need, or drop a file into the popup. Everything is decoded and re-encoded on your own computer, so holiday photos, screenshots, client artwork and confidential scans never leave your device. No account, no ads, no tracking.

Everything it does

The core features at a glance.

01

Convert any image on any page from the right-click menu: Save as PNG, JPG, WebP or AVIF, or Copy as PNG.

02

Four output formats: PNG for transparency, JPG for compatibility, WebP for smaller photos, AVIF for the smallest file.

03

Local files by drag and drop or paste, with the same quality controls.

04

HEIC and HEIF input, so iPhone photos convert without an online service.

05

Resize while converting: scale by percentage from 5% to 200%, or type exact pixel dimensions and leave one field empty to keep the aspect ratio.

06

Quality sliders from 10 to 100 for JPG, WebP and AVIF. PNG stays lossless.

Also included

  • Before and after size in the confirmation, with the real saving in percent.
  • Transparent areas become white in JPG instead of black, so logos do not turn into dark rectangles.
  • Smart link cleaning: tracking parameters added by image CDNs are stripped before the image is fetched.
  • Images inside links, lazy-loaded pictures and cross-origin images are handled the same way.
  • Batch export from a page: list every loaded image, filter by size, tick what you want and export together.

Free vs Premium

The free tier is a complete tool, not a trial. Premium is optional.

Free

right-click conversion, copy as PNG, drag and drop, paste, HEIC input, resize, quality sliders, link cleaning, size comparison, up to 5 dropped files at a time, and batch export of up to 5 page images per run.

Premium

no cap on dropped or pasted files, up to 100 images from a page per run, ZIP delivery, up to 12 batch presets, and filename templates. One key activates on two browsers, and removing the licence from one browser frees that slot again.

No licence is needed to convert single images, and every free feature works without an account. Premium asks the licence server for a check about every two hours. It keeps working while you are offline; a failed check never switches the paid features off.

Private by design

Your data stays on your device. No account, no analytics, no tracking. Read exactly what is stored and when the extension uses the network.

💌 A Note to You

Thank you for using ImageConv. I built this tool because I was tired of online converters that require uploading files, waiting forever, and risking my privacy.

If it helps you too, that's already the best reward I could ask for.

Of course, if you'd like to ☕ buy me a coffee, it would truly make my day — and keep me motivated to make ImageConv even better.
