Frequently Asked Questions
Is there a limit to how many images I can resize at once?
There is no hard software limit; however, because the tool uses your local browser memory, performance depends on your device’s RAM. We recommend batches of up to 50–100 images for the smoothest experience.
Will resizing my images reduce their quality?
Resizing inherently changes pixel density, but you can control the output quality percentage. Setting it to 80-90% typically offers the best balance between small file size and high visual fidelity.
Are my private photos uploaded to your servers?
No. This tool is 100% client-side. All processing happens within your browser’s local environment, meaning your images are never transmitted or stored on any external server.
What file formats are supported for bulk conversion?
The tool supports standard web formats including JPEG, PNG, and WEBP for both input and output, allowing you to convert formats while resizing.
Does the tool maintain the original aspect ratio?
Yes. By setting either a maximum width or height, the tool automatically calculates the other dimension to ensure your images do not look stretched or distorted.
Can I use this tool on a mobile device?
Yes, the Bulk Image Resizer is fully responsive and works on mobile browsers, though processing very large batches may be faster on a desktop computer.
