Metadata Stripper
Strip EXIF and GPS data from photos client-side
Drop an image here or click to select
JPEG, PNG, WebP
使い方
Drop or select an image file (JPEG, PNG, WebP). The tool reads the file in your browser and shows any metadata found (camera model, GPS coordinates, software, dates). Click the strip button to create a clean copy with all metadata removed. The clean image is generated by re-drawing through an HTML Canvas, which preserves only pixel data. Your image never leaves your device.
例
Remove GPS from a phone photo
Most smartphone photos embed your exact GPS coordinates in EXIF data. Before sharing on forums, classifieds, or social media, strip the metadata to prevent others from seeing where the photo was taken.
Clean images before uploading to a website
EXIF data adds unnecessary file size (often 5-50 KB per image). Stripping metadata before uploading to your website reduces file sizes and removes potentially sensitive information like camera serial numbers and editing software.
Privacy compliance
Under GDPR, GPS coordinates in photos can be personal data. If you collect user-uploaded images, strip metadata on the client side before uploading to your server. This tool demonstrates the technique using the Canvas API.
よくある質問
What metadata does this tool remove?
This tool removes all non-pixel data: EXIF (camera settings, GPS, dates, device info), IPTC (captions, keywords, copyright), XMP (Adobe metadata), ICC color profiles, and any other embedded data. The output contains only the image pixels at the same dimensions and visual quality.
画像はサーバーにアップロードされますか?
No. The entire process runs in your browser using JavaScript. The image is read locally, drawn to an HTML Canvas element, and exported as a clean file. No network requests are made. You can verify this by disconnecting from the internet and using the tool offline.
Does stripping metadata reduce image quality?
The canvas export uses a quality setting of 0.92 (92%) for JPEG, which is visually indistinguishable from the original for most photos. The file size may change slightly. PNG export is lossless. For professional photography where every bit matters, use dedicated EXIF editing software instead.
What types of images are supported?
JPEG, PNG, and WebP files are supported. These cover the vast majority of photos and web images. RAW camera files (CR2, NEF, ARW) are not supported because browsers cannot render them directly.
Why do photos contain GPS data?
Most smartphones enable geotagging by default, embedding your latitude and longitude in every photo. This is stored in the EXIF GPS IFD section. Social media platforms like Facebook and Instagram automatically strip this data on upload, but many other platforms (forums, email, file sharing) do not.
