FAQ
Is it free?
Yes, completely free. No signup, no limits.
What input methods?
3 methods: drag-and-drop, clipboard paste, click to upload.
Will images be uploaded?
No. Entire process local; images never leave your computer.
What output formats?
4 formats: Data URI, CSS bg, HTML img, JSON.
Can I compress first?
Yes. Optional compression with adjustable quality/size.
Is this tool suitable for ecommerce, social media, or email images?
Yes. Ecommerce images usually need clean edges and consistent sizing, social images need stronger cropping and visual impact, and email images need smaller file sizes. Export different sizes for each target channel.
Are my images uploaded to a server?
Most image tools on the site prioritize local browser-side processing, which is better for privacy-sensitive assets. If any AI feature has a usage cap or depends on a cloud model, the page copy will call that out explicitly.
How do I choose between PNG, JPG, and WebP?
Choose PNG for transparent backgrounds, JPG for photos and heavier compression, and WebP when you want a better balance of quality and file size. If your target platform requires a specific format, follow that first.
Do I need to sign up, download, or install anything?
Most Gotokit tools are designed to open directly in the browser without a separate install. If a tool has a quota, browser requirement, or third-party dependency, the page copy will state that clearly.
