Guides and upload help
Read practical guidance before choosing settings for file size, formats, private processing and rejected uploads.
How to compress an image without uploading it
No-upload compression means your selected image is handled on your device for the tool workflow instead of being sent to a server for processing.
Image file size guide for uploads
Image file size depends on dimensions, format, compression settings and image detail. The same 1200 x 800 image can be small or huge depending on what it contains.
JPEG vs PNG vs WebP
JPEG, PNG and WebP solve different problems. The best format depends on whether you need small photo files, transparency, sharp graphics or broad upload compatibility.
How to reduce image size for online forms
When a form rejects an image, the issue is usually file size, dimensions, format, or a combination of those settings.
How to compress an image for email
