Frequently asked questions
Is this really free?
Yes, completely. toolmonkey resizes images with no subscription, no trial, and no catch. It's supported by ads, not fees.
Do my images get uploaded to a server?
No. Resizing runs entirely in your browser using the Canvas API. Your file never touches toolmonkey's servers.
Does resizing change the file format?
No. The output keeps the same format as your original file — a JPG stays a JPG, a PNG stays a PNG. Need to convert format too? Use PNG to JPG or JPG to PNG.
Can I resize an image to be larger than the original?
Yes, but enlarging beyond the original dimensions can make the image look soft or blurry, since no new detail is added.
Is there a file size limit?
Yes. toolmonkey accepts images up to 20 MB. For larger files, consider reducing the resolution before uploading.
