Image inspection
- Example
admin-dashboard.webp · 35KB source- Result
1181×649 · 0.77MP · ratio 1181:649 320px estimate 320×176 · 2KB
The thumbnail byte count is clearly labeled as a planning estimate, not an encoded output measurement.
Inspect image details, resize and convert to WebP, and review EXIF metadata on one page.
Selected images are never uploaded; all processing happens inside your browser.
Check image dimensions, aspect ratio, megapixels, and thumbnail estimates in the browser without uploading.
Shrink images and convert them to WebP or JPEG in the browser, then download the results. Original files stay untouched.
Check shooting details and whether GPS location is embedded in JPG photos. Useful before sharing pictures.
This example uses admin-dashboard.webp from this site’s Palworld server-admin article to show both inspection and conversion results.

640px max width · WebP · quality 8035KB → 13KB · output 640×352Browser encoders can differ by a few bytes, so measure a representative batch before setting production defaults.
After checking in the browser tool, batch processing is easiest with one ImageMagick line.
# 0) install ImageMagick (provides mogrify and identify)
sudo apt install -y imagemagick
# 1) batch-downscale a folder to 1600px wide (ratio kept)
# ⚠ mogrify overwrites originals — back up first
cp -r . ../backup_originals
mogrify -resize 1600x *.jpg
# → finishing silently means success (no error = OK)
# 2) re-save at quality 85 to cut file size
mogrify -quality 85 *.jpg
# 3) verify the result by dimensions and size
identify -format "%f %wx%h %b\\n" *.jpg
# → photo.jpg 1600x900 240KB
