Image Guides
Practical how-tos for the things people actually need to do with images. Every recommendation here is backed by a measurement from our research section — when we say "quality 60", we can show you the file sizes and fidelity numbers behind it.

How to Compress Images for the Web Without Wrecking Them
A decision procedure, not vibes: pick the delivery width first (it's worth more than any quality setting), then the right quality per content type — and avoid the quality-70 trap zone we measured on screenshots and flat art.
JPEG, PNG or WebP? A Decision Guide With Numbers
One table, one decision per content type: photos (WebP saves ~31% at matched fidelity), screenshots (WebP wins both axes), documents (lossless WebP, 3.6× smaller than PNG) — plus the case where lossless WebP actually loses.
What Size Should a Photo Be for Email and Social Media?
Straight answers in pixels, with the file-size consequences measured: why an 800px email photo weighs 52 KB while the same photo at full resolution weighs 190+ KB at identical quality — and when to keep the original instead.
Remove EXIF (and Your Location) Before Sharing Photos
One photo can carry 26 metadata fields, including GPS coordinates to a few meters. Which operations actually strip them (measured: 6 of 7), which preserve them, and a 2-minute routine before you share anything.
Batch-Processing Product Photos for Your Online Store
A repeatable pipeline for catalogs: standard width, one quality setting, one format — with the arithmetic of why 100 product shots at the right settings weigh less than 5 original photos did.
Where the Numbers Come From
Every guide cites measurements from our research studies — JPEG quality sweeps, WebP vs JPEG comparisons, resizing experiments, EXIF survival tests, and network-level comparisons of processing architectures. If you want the data rather than the advice, start here:
