FAQ
Is it free?
Yes, completely free. No signup required. First 100 calls per month are free, always available.
How much larger?
Supports 1x (enhance at original resolution), 2x, 3x, 4x enlargement. E.g., a 1000×800 image becomes 2000×1600 at 2x.
What formats?
JPG, JPEG, PNG, BMP, WEBP, HEIC. 5MB file limit, max 1920×1080px.
Standard vs Enhanced?
Standard mode focuses on natural enlargement. Enhanced mode further sharpens edges and textures, ideal for restoring old photos and low-quality assets.
Will images be saved?
No. Temporarily used during processing, automatically deleted afterwards.
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.
