Strip metadata from many images at once

Drop in any number of JPEGs and PNGs and strip every metadata segment in a single pass. No pixel data is re-encoded — zero quality loss.

Quick Start

How it works

Pick an image, tune the options, then download the result. Everything runs in your browser.

  1. 01

    Pick files

    Drop in JPEGs and PNGs. The tool sniffs the magic bytes to detect format.

    Files stay in memory as an HTMLImageElement — the original bytes are never uploaded, and EXIF metadata is preserved until you explicitly transform it.

    JPEG: strip APP

    APP1 (EXIF/XMP), APP13 (IPTC), APP2 (ICC) and comment markers are removed.

    Encoder quality is exposed where the format supports it — JPEG and WebP get a 0–1 quality slider; PNG is lossless. Options re-render the canvas immediately.

    PNG: ancillary chunks

    Only IHDR, IDAT, IEND survive. tEXt/iTXt/gAMA and friends are dropped.

    Pixel work runs on the Canvas 2D context — drawImage resamples with the browser’s bilinear filter and getImageData/putImageData back per-pixel passes.

    Download

    Save per file or all at once. Pixel data is untouched — zero re-encoding.

    Downloads ship via a hidden anchor with an object URL — no server round-trip, and the file on disk is untouched. The output filename inherits a sensible suffix.

Pro tips

Browser-only image work that scales

Convert with quality control

JPEG/WebP let you pick a 0–1 quality. Default 0.92 is a good compromise of size and visible quality.

PNG isn’t free

Use PNG only for transparency or sharp edges. For photos, WebP is smaller at the same perceived quality.

Strip EXIF for privacy

Photo EXIF often contains GPS, camera model, and timestamps. Strip before sharing public uploads.

Watch the colour profile

Convert to sRGB before web export. Wide-gamut images render oversaturated in non-managed browsers.

AVIF when it’s available

AVIF beats WebP on size at the same quality. Detect support via <picture> with fallbacks.

Lazy-load below the fold

Add loading="lazy" on <img>. The browser handles scheduling — no IntersectionObserver needed.

Use Cases

When to use this tool

Common workflows it speeds up.

Pre-publish hygiene

Strip EXIF before posting photos online. Decoded into a Canvas 2D context — original bytes never leave the tab, so you can process customer-uploaded photos, internal screenshots, or sensitive diagrams without privacy concerns.

px-perfect

Vendor handoff

Remove IPTC keywords from shared assets. Encoders expose quality 0–1 where the format supports it (JPEG, WebP); PNG and AVIF stay perceptually lossless. Pick 0.85 for web, 0.95 for archival, 0.7 for thumbnails.

quality-tunable

Forensics scrub

Drop GPS and camera serials in one click. Pair with the EXIF Stripper before sharing user-uploaded photos publicly. Camera serial numbers, GPS coordinates, and timestamps often hide in image metadata and leak more than the picture itself.

format-aware

Build pipeline

Slim image assets bundled with apps. Output preserves colour profile (sRGB) so it renders consistently across browsers, monitors, and print pipelines. Wide-gamut workflows can opt into Display P3 for modern Apple devices.

EXIF-safe

Fast triage

Faster than scripting an exiftool run. Re-runs only on option changes, never on window resize, so the canvas stays responsive on large images. drawImage uses the browser's bilinear filter for fast resampling.

client-side

Social posting

Avoid leaking location with each upload. Downloads as .png, .jpg, .webp, or .avif with the correct MIME so editors apply native handling on save. The filename inherits a sensible suffix derived from the input.

FAQ

Frequently asked questions

No. Both pipelines edit the container in place — no pixel data is decoded or re-compressed, so there&apos;s zero quality loss.
JPEG and PNG. Other formats are skipped with a warning per file.
Yes — GPS lives in EXIF/APP1 for JPEG and in optional chunks for PNG. Both pipelines drop them.
No. All stripping runs locally in your browser — your files never leave the device.
Most PNGs already carry little metadata. The savings depend on what was in the source.
