Open any image — without uploading it

Drop a common image format and OmniViewer previews it, inspects its exact bytes, views or edits the supported metadata, cleans several files at once, and builds a local slideshow. Everything runs in your browser — no upload, no server.

Formats with a dedicated toolkit

PNG — a full image editor (crop, resize, rotate, filters, background removal), a chunk explorer with CRC verdicts, metadata editing and stripping, a steganography tab, and stats.

JPG, GIF, WebP, HEIC and SVG open in the preview with a colour palette and a byte-exact hex view, plus metadata and batch tag-cleaning where the format allows; PNG gets the deeper editing and inspection tools. The image is read locally, so it never leaves your computer.

FAQ

Is my image uploaded anywhere?

No. OmniViewer is a static page with no server-side processing: your image is read directly by your browser and never leaves your computer.

Which image formats are supported?

PNG has a dedicated toolkit — a full editor (crop, resize, rotate, filters, background removal), a chunk explorer with CRC verdicts, metadata editing and stripping, a steganography tab, and stats. JPG, JPEG, GIF, WebP, HEIC and SVG open in the preview with a colour palette and a hex view. Format is detected from the content, not the extension.

Can I remove EXIF or GPS data from an image?

Yes. For PNG, OmniViewer strips text chunks, XMP and the eXIf block (including any GPS position) by pure byte surgery, leaving the pixels bit-identical. Other formats expose the metadata they carry in the viewer.
