↓ 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 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, HEIC and WebP 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, HEIC and WebP 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. WebP gets a lossy/lossless verdict with an estimated quality, conversion to PNG, JPG or animated PNG, a frame-by-frame view of animations, and EXIF/GPS, XMP and C2PA stripping. GIF 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, and for WebP it rewrites the file without its EXIF, XMP and C2PA chunks. Other formats expose the metadata they carry in the viewer.
