About Batch Image Resizer & Converter
Each image is decoded into an in-memory <canvas>, scaled down (never up) while preserving its aspect ratio, and re-encoded with the canvas at your chosen quality. Because resizing and encoding happen in your browser, large photo folders are processed without uploading gigabytes to a server. Batch size caps and the download-all queue scale with your subscription tier.
Frequently Asked Questions
How many images can I resize at once?
Your plan sets the cap: 20 on Free/preview, 100 on Pro, and 500 on Business.
Can it upscale small images?
It only scales down to the maximum dimensions so you never lose quality by enlarging.
Are my photos uploaded?
No. All resizing and encoding run in your browser via the canvas API.
Which output formats are supported?
JPG, PNG, and WebP, with a quality slider for the lossy formats.
