↓ scroll for about & FAQDrop 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.
GIF, WebP 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, JPG and HEIC get the deeper inspection tools. The image is read locally, so it never leaves your computer.
No. OmniViewer is a static page with no server-side processing: your image is read directly by your browser and never leaves your computer.
PNG, JPG and HEIC each have a dedicated toolkit. PNG gets 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 gets EXIF/GPS reading and stripping, a marker-segment explorer, a quality estimate from the quantization tables, and a colour palette. HEIC gets EXIF/GPS reading and stripping, an ISO-BMFF item-structure explorer, and the HEVC profile and dimensions — without converting to JPG. GIF, WebP and SVG open in the preview with a colour palette and a hex view. Format is detected from the content, not the extension.
Yes. For JPG, OmniViewer reads the EXIF a camera wrote — including any GPS position — and strips the EXIF, XMP and every metadata segment by pure byte surgery, leaving the compressed image pixel-identical. For PNG, it strips text chunks, XMP and the eXIf block the same way. Other formats expose the metadata they carry in the viewer.
