Collection
Image Tools
Use this collection when a picture needs to change size, weight or format without a trip to someone else’s server. Shrink a photo, crop it, switch between common image types, read a colour, build a favicon package, lay out a poster, or print a passport-size sheet. The work happens in the tab you already have open.

FAQ
Image Tools: common questions
What belongs in Image Tools on Toolspire?
Image Tools is one collection on justtools.info. Open any tool and the page tells you whether the work stays on your device or a public lookup is required.
Are my images uploaded to a server?
No. Every image tool on Toolspire processes files locally in this tab with the Canvas and File APIs. Your photos stay on this device, so they cannot be stored, shared or used for training.
Which image formats are supported?
JPG/JPEG, PNG, WebP, GIF and BMP work in every modern browser. AVIF and HEIC depend on the decoders built into your browser — Safari, for example, can open iPhone HEIC photos while Chrome cannot.
Is there a limit on file size or the number of images?
There is no artificial limit and no daily quota. Very large images are limited only by your device’s memory.
