Answers for this tool. For site-wide help, open the FAQ hub.
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.
