Hey Startupbase Hunters! 👋

I'm excited to share ResizeImage.dev with you today.

I built it around a very simple idea: basic image editing shouldn't require uploading your files to a server, creating an account, or opening a heavy image editor.

I often just need to resize an image to an exact size, compress it, convert the format, or process several images at once. Most online tools can do this, but many require uploads, sign-ups, have usage limits, or add watermarks.

So I built ResizeImage.dev — a collection of simple image tools that work directly in your browser.

Today you can use it to:

→ Resize & crop images → Bulk resize multiple images → Compress images → Convert image formats → Stitch images together → Remove Gemini watermarks

Everything is designed to be fast and straightforward.

🔒 Images are processed locally in your browser
🆓 Free to use
🚫 No account required
🚫 No watermarks
♾️ No usage limits

I'm planning to keep adding useful image tools while keeping the same philosophy: open the page, do the job, and leave.

I'd love to hear what you think — especially which image tool you'd like me to build next.

Thanks for checking it out! ❤️
