Frequently asked questions

Is my image uploaded to your servers?
No. All processing happens in your browser using the HTML5 Canvas API. Your images never leave your device.
Which image formats are supported?
The tool accepts JPEG, PNG and WebP files as input. You can convert to any of these formats as output.
Can I enlarge an image beyond its original size?
Yes. The percentage slider goes up to 200% and you can enter any pixel dimensions. Keep in mind that enlarging may reduce sharpness.
How do I keep the aspect ratio when resizing?
In Exact Pixels mode, enable the aspect ratio lock (🔗 icon) so the height is calculated automatically from the width. In Percentage mode, proportions are always preserved.
Which social media presets are available?
Presets are available for Instagram (square 1080×1080, story 1080×1920), Pinterest (1000×1500), X/Facebook (1200×675), YouTube (1280×720), Facebook/LinkedIn banner (820×312) and Full HD (1920×1080).
