Design asked for a 1200×630 social image and your export is 4000px wide. Image Resizer scales by pixels, percent, or print units with an aspect lock so you do not stretch faces by accident.
Resize for Open Graph cards, app icons, email banners, or CMS max dimensions. Lock aspect ratio unless you intentionally need a crop workflow elsewhere. Changing dimensions is not the same as compressing file weight; pair with Image Compressor when the byte size is still too high.
Pitfall: upscaling a tiny logo and expecting print sharpness. You cannot invent detail that was never in the pixels.
Tip: set the long edge for web hero images and let height follow with aspect lock on.

Image tools process pixels in the browser with Canvas and related APIs. Images are not uploaded to OneDevToolkit for these client-side jobs.
PNG, JPEG, and WebP are widely supported. Some tools also accept GIF or SVG depending on the operation.
Lossless operations keep quality; JPEG/WebP compression trades quality for size. Use higher quality settings when print fidelity matters.
Yes for tools that preserve alpha. Converting to JPEG removes transparency - keep PNG/WebP when you need an alpha channel.
Limits come from browser memory. Extremely large megapixel images may fail - downscale first if needed.
Many image studios show preview panels. Download both versions if you need an external comparison.
Some tools intentionally remove EXIF; others preserve pixels only. Check the tool description for metadata behaviour.
If the UI shows a multi-file queue, yes. Otherwise process files one by one or script downloads locally after each run.
HEIC from some phones may need conversion to JPEG/PNG first. Export from Photos as JPEG when uploads fail.
