How to use Image converter

Drop one or more images, choose the output format, and adjust quality (JPG, WebP, PDF) or the background color (JPG). For SVG, set the output width. For PDF, pick A4, Letter, or image-sized pages; all files go into one PDF. Tap Convert and download the files or a ZIP.

Add your file

Drag & drop, browse files, or press Ctrl+V to paste from the clipboard where supported.

Process in the browser

Work stays in this tab with WebAssembly, Canvas, or other on-device APIs — your file is not uploaded to Omnipus.

Download or share

Save the result to your device, or share it with the OS share sheet when available.

Direct share: Install Omnipus as an app on Android to share files and links into this tool from other apps.

About this tool

One converter for the formats people actually run into. Inputs: JPG, PNG, WebP, HEIC/HEIF (iPhone), AVIF, GIF, SVG, BMP, and ICO. Outputs: PNG, JPG, WebP, multi-size ICO favicons, or a single PDF with one image per page. Decoding uses the browser (plus a HEIC decoder when the browser has none) and encoding uses canvas and pdf-lib, so files stay on your device. Animated GIF and WebP keep only the first frame, and JPG has no transparency, so transparent areas get the background color you choose.

Frequently Asked Questions

Which formats can it read?

Anything the browser can decode — JPG, PNG, WebP, GIF, SVG, BMP, ICO, and AVIF in current browsers — plus HEIC/HEIF via a built-in decoder.

Can it output AVIF, TIFF, or BMP?

Not yet. Browsers cannot reliably encode those formats, so the outputs are PNG, JPG, WebP, ICO, and PDF.

What happens to transparency?

PNG, WebP, and ICO keep it. JPG and PDF pages are opaque, so transparent areas are filled with your background color (white by default).

Are animated GIFs kept animated?

No. Still formats keep only the first frame. Use Video converter to turn a video into an animated GIF.

Are my images uploaded?

No. Conversion runs in this tab.

Is Image converter completely free to use?

Yes. Image converter on Omnipus is free to use with no subscription paywall for the tool itself.

Are my files or data uploaded to any servers?

No. Image converter processes your input locally in this browser tab. Your files and text are not sent to Omnipus. Some tools download an engine or model file the first time you use them; that is a download, not an upload.

Does Omnipus add watermarks to exported files?

No. Omnipus does not stamp a site watermark onto files you export from Image converter.

Can I use Image converter on my mobile phone?

Yes. Omnipus has touch-friendly controls and can be installed as an app. On Android you can also share files or links into tools from other apps.
