Frequently Asked Questions

Q: Which output format should I choose?

PNG: Best for illustrations, logos, and images with transparency. Lossless compression with no quality degradation.
JPEG: Best for photos. Significant file size reduction possible with quality settings.
WebP: Modern format achieving about 30% smaller file size than JPEG. Supports transparency and optional lossless compression.

Q: Why lock aspect ratio?

Locking aspect ratio ensures images resize naturally without distortion. It's recommended to keep this ON for product images, portraits, and when maintaining the original shape is important.

Q: How to efficiently process multiple images?

Drag and drop multiple files at once, then click "Resize All" for batch processing. After processing, download all images as a ZIP file. Use presets for quick sizing for social media or print purposes.

Q: Can I adjust image quality?

JPEG and WebP quality can be fine-tuned from 10-100% using the quality slider. See the "Quality Settings Guide" below for recommended values. PNG uses lossless compression, so quality settings are not needed.

Q: Can I customize filenames?

Custom settings allow adding prefix/suffix text and automatically appending size information (e.g., _800x600). This is convenient for batch processing multiple files.

Quality Settings Guide

JPEG Format Recommendations

High Quality
90%
Maintains stable high quality for any image. Ideal for printing and long-term storage.
Size Priority
75%
Degradation noticeable only upon close inspection, almost indistinguishable during normal viewing. Below this, mosquito noise begins to become noticeable.

WebP Format Recommendations

Lossless
Checkbox ON
Use when complete quality preservation is needed for transparent images or illustrations. Ideal PNG replacement.
Size Priority
70%
Below 70%, file size reduction diminishes while quality continues to decrease.
