EXIF Data Viewer/Remover

The EXIF Data Viewer & Remover reads the metadata that your camera, phone or editing software hides inside every photo — manufacturer, lens, exposure, GPS coordinates, software, copyright, and dozens more — and lets you wipe it before you share. The viewer parses the raw bytes directly in your browser using the File API and a JavaScript EXIF reader, then either rewrites the JPEG losslessly (preserving every pixel) or re-encodes the image through a Canvas to guarantee a metadata-free copy.

What Makes This Tool Different

How to Use

1. Drop, paste, or pick a sample. Drag a photo onto the drop zone, click to browse, paste from your clipboard, or try one of the sample photos (DSLR landscape, smartphone selfie, edited screenshot).
2. Read the inspection report. The summary strip shows total tags, whether GPS is present, how many software/author tags there are, and the file size. Below it, six panels break the tags into Camera & Lens, Exposure, GPS, Date & Time, Software & Author and Image Properties.
3. Choose what to strip. Pick Strip everything (the safest default), GPS only, Software, author, copyright only, or Keep orientation (drops everything but the rotation flag so your photo stays right-side up).
4. Pick an output format. Same as input keeps JPEG losslessly. Choose JPEG, PNG, or WebP to convert at the same time. JPEG/WebP exports also expose a quality slider.
5. Download the clean copy. Click Strip & download in the inspection report — your browser saves filename-clean.jpg (or .png/.webp). The size difference vs. the original is shown so you can confirm metadata was actually removed.

Anatomy of a JPEG File

A JPEG is a sequence of marker segments. Every segment starts with the byte 0xFF followed by a marker byte. The metadata blocks live in the APP1, APP2, APP13 and APP14 segments — they are completely separate from the actual compressed image data. Removing them does not change a single pixel.

The first three coloured blocks contain metadata and can be stripped without re-encoding. The green block is the actual image — the stripper preserves it byte-for-byte. This is why JPEG removal in this tool is truly lossless.

What Each Tag Group Means

📷 Camera & Lens

Manufacturer (Make), body (Model), lens (LensModel), and serial numbers. Sharing these reveals exactly what gear you own — relevant for theft and targeted advertising. Pro photographers also share intentionally for portfolios.

⚙ Exposure

Shutter speed, aperture (f-number), ISO, focal length, flash, and metering mode. Useful for portfolios and Lightroom-style "shot info"; harmless on its own.

📍 GPS & Location

Latitude, longitude, altitude, direction, and a UTC timestamp — accurate to a few meters. This is the metadata most worth removing. A single photo with GPS shared online can reveal your home address, your child’s school, or the location of a confidential meeting.

🕐 Date & Time

DateTimeOriginal (when the shutter fired), DateTimeDigitized (sensor → file), ModifyDate (last save), and the time-zone offsets. Useful for chronological sorting but can reveal patterns of behavior.

🧑💻 Software & Author

Editing app and version (Software), photographer name (Artist), copyright string, and the unique image ID. Strip when you don’t want recipients to know how the photo was processed or who authored it.

🖼 Image Properties

Pixel dimensions, orientation, color space (sRGB vs. Display P3), resolution (dpi), and compression. Orientation is the one tag that often needs to stay — without it, some viewers display vertical phone photos sideways.

Privacy: How Bad Is EXIF, Really?

By default, every modern smartphone embeds GPS coordinates accurate to within a few meters into every photo. When you email a photo, post it to a forum or chat, upload it to a cloud-shared folder, or hand it to a printer, the GPS goes with it. Stalking, doxxing, and home burglaries traced back to GPS-tagged photos are well-documented. Even when the platform strips EXIF for the public-facing image, the original is often retained on the server — and EXIF survives any download link, AirDrop, or direct file transfer.

Some platforms strip EXIF (Facebook, Instagram, Twitter for public viewers), while many others preserve it (Discord attachments, Telegram non-compressed sends, GitHub commits, plain email, Slack file uploads, personal blogs, image hosting sites). When you’re not sure — strip it first.

Lossless vs. Re-encoded Stripping

Lossless (JPEG only). The tool walks each 0xFF[marker] segment in the file, copies the SOI, image-data and EOI segments verbatim, and skips the APP1/APP13/APP14 metadata segments. The output is bit-perfect identical to the original wherever pixel data lives.

Re-encoded (PNG, WebP, or conversion). The image is drawn onto an HTML5 Canvas and exported via canvas.toBlob(). This naturally drops all metadata because the Canvas API does not preserve EXIF or any embedded text chunks. The trade-off is a small quality loss for lossy formats — controlled by the quality slider.

Browser Compatibility

• JPEG / JPG — view + strip (lossless) — all browsers.
• PNG, WebP — view dimensions + re-encode to strip — all browsers.
• TIFF — view dimensions + re-encode — Safari decodes natively, Chrome/Firefox may need a separate viewer.
• HEIC / HEIF — viewing depends on browser support. Safari (Mac/iOS) decodes natively. On Chrome and Firefox you may need to convert HEIC to JPEG first.

Where This Tool Shines

• Selling or trading anything online — Marketplace, Craigslist, eBay listings often leak the seller’s home GPS.
• Renting your home — Photos for Airbnb, Vrbo, classified ads, and short-term rentals.
• Public-figure photo releases — Press, PR teams, journalists checking incoming assets.
• Children’s photos — Birthday and school photos shared in family chats.
• Activists, journalists, whistleblowers — Sources need to verify a photo carries no identifying metadata before publication.
• Portfolio cleanup — Photographers wiping copyright or watermark traces before posting low-res previews.
• Forensic / archival inspection — Decode every tag, copy as JSON, store alongside the source file.

FAQ

Are my photos uploaded anywhere?

No. The EXIF Data Viewer & Remover is 100% client-side. Your photo is read into the browser using the File API, parsed in JavaScript, and the cleaned version is downloaded directly — nothing is ever sent to a server. The only network request the tool may make is loading the OpenStreetMap tile that shows your photo’s GPS location, and that only happens if the photo actually contains GPS coordinates.

Does removing EXIF reduce image quality?

No, as long as you keep the original format. For JPEG, the tool uses lossless segment-walking that drops only the metadata segments (APP1, APP13, APP14) but keeps every pixel byte intact. If you choose to convert to a different format (PNG → JPEG, JPEG → WebP), the image is re-encoded and may lose a small amount of quality.

What is EXIF and why should I remove it?

EXIF (Exchangeable Image File Format) is metadata that cameras and phones embed in photos: camera model, lens, exposure settings, software, copyright and very often GPS coordinates. Sharing a photo with EXIF can leak your home address, daily routine, or the gear you own — even when the visible image looks completely innocuous.

Does this remove GPS location data?

Yes. The GPS panel surfaces every coordinate, altitude and timestamp tag, and choosing Strip GPS only or Strip everything removes the entire GPS IFD from the file. If GPS is present, an OpenStreetMap preview is also shown so you can see at a glance what would be leaked.

Which file formats are supported?

JPEG/JPG for full lossless strip with detailed tag decoding. PNG and WebP for re-encoded stripping. TIFF for viewing. HEIC/HEIF viewing depends on your browser — Safari decodes it natively, Chrome and Firefox typically need a conversion first.

Does Facebook or Instagram already strip EXIF?

Most large social networks strip EXIF before showing the photo to other users, but the original is often kept on their servers. For email, Discord attachments, Telegram non-compressed sends, GitHub commits, personal blogs, cloud-shared folders, AirDrop and direct file transfers, EXIF is preserved as-is — that is where you should strip it first.

Can I keep the orientation tag so vertical photos stay upright?

Yes. Choose Strip everything but keep orientation. The tool builds a minimal APP1 segment that contains only the orientation flag and drops everything else.

Can I batch-process a folder of photos?

This tool processes one photo at a time. For batch jobs of many photos, a desktop tool like exiftool is the better fit. This tool is optimized for the case where you want to see what is in a photo and verify it’s clean before sharing.

Will recipients know I stripped metadata?

No. A stripped photo simply has no EXIF block — which is the same as a screenshot, a freshly painted image, or a photo that was downloaded and re-uploaded through a service that strips metadata. There is no visible "stripped" flag.
