Keep an untouched original
Resizing and lossy encoding discard information. Export derivatives for each use and retain the highest-quality source separately.
Images and media guide
Prepare files for their final placement—not an abstract score
Compression, cropping and QR generation are production tasks. The right output is the smallest or simplest file that still works in its intended placement, at its intended size, on real devices.
Preserve the source, then create purpose-built outputs
Use Image Compressor for dimensions, format and file-size work; Social Crop Studio for coordinated aspect ratios and subject placement; and QR Toolkit to create or inspect machine-readable codes. These tools process selected files locally in the browser.
Test at final size
A crop that looks clear in a large preview may fail as a thumbnail. A QR code that scans on screen may fail after printing or resizing.
Expect platforms to change
Preset dimensions are starting points. Confirm current platform specifications before a major campaign or paid placement.
Before relying on a result
- Use sufficient source resolution.
- Inspect every extreme aspect ratio.
- Check contrast and quiet space around QR codes.
- Test downloaded files in the actual destination.
