Pull GPS coordinates from a photo
Read latitude, longitude, altitude, and a one-click map link from any geotagged JPEG. Runs entirely in your browser.

How it works
Pick an image, tune the options, then download the result. Everything runs in your browser.
- 01
Drop a JPEG
The photo needs an EXIF GPS block — most phones include one by default.
Files stay in memory as an
HTMLImageElement— the original bytes are never uploaded, and EXIF metadata is preserved until you explicitly transform it.jpeguploadcanvaslocaldecodeinput · bytesgeotagged · loadedphoto.jpg

Parse the EXIF
The APP1 EXIF segment contains a GPS IFD with lat/lng/alt rationals.
Encoder quality is exposed where the format supports it — JPEG and WebP get a
0–1quality slider; PNG is lossless. Options re-render the canvas immediately.parseoptionslive previewencoderqualityifd · tunablegps · liveGPSLatitude · GPSLongitude · GPSAltitude

Both decimal and degrees/minutes/seconds are shown, copy-ready.

One click to Google Maps or OpenStreetMap.
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.

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.
When to use this tool
Common workflows it speeds up.
Photo journals
Map the route a trip's photos took. 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-perfectReal estate
Pull location from listing photos for verification. 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-tunableField reports
Auto-locate inspection or survey shots. 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-awareOSINT
Geolocate evidence images quickly. 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-safePhoto library
Cluster pictures on a map of your trips. 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-sideMap-based UIs
Bootstrap data for a custom map view. 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.
