Question 1

What image formats are supported?

Accepted Answer

Triim supports PNG and WebP images with transparency (alpha channel). These are the most common formats for images with transparent backgrounds used in web design, graphic design, and e-commerce.

Question 2

Is there a file size limit?

Accepted Answer

Currently, you can process images up to a reasonable size. For best performance, we recommend keeping individual files under 10MB. You can process multiple images at once in batch mode.

Question 3

Is my data safe? Do you store my images?

Accepted Answer

Yes. Triim is a static site — every image you select is decoded, trimmed, and re-encoded entirely inside your browser. Your files are never uploaded to a server, so there is nothing for us (or anyone else) to store.

Question 4

How does the trimming work?

Accepted Answer

Triim analyzes the alpha channel (transparency) of your image and automatically detects and removes transparent pixels from all edges. This results in a perfectly cropped image with no unnecessary transparent borders, reducing file size and improving web performance.

Question 5

Can I process multiple images at once?

Accepted Answer

Yes! You can upload multiple PNG or WebP images and process them all at once. After processing, you can download them individually or as a convenient ZIP file containing all trimmed images.

Question 6

Will trimming reduce my file size?

Accepted Answer

Yes! Removing transparent pixels reduces the overall dimensions of your image, which typically results in a smaller file size. This is especially beneficial for web performance, faster page loads, and reduced storage requirements.

Question 7

What are common use cases for trimming transparent pixels?

Accepted Answer

Triim is perfect for graphic designers cleaning up exported assets, web developers optimizing images for websites, e-commerce sellers preparing product photos, UI/UX designers creating clean interfaces, and anyone working with logos, icons, or graphics that need precise boundaries without unnecessary transparent space.

Question 8

Is Triim really free?

Accepted Answer

Yes, completely free! No sign-up required, no hidden fees, no watermarks, and no credit card needed. We believe in providing useful tools accessible to everyone.

Question 9

Can I use this for commercial projects?

Accepted Answer

Absolutely! Triim is free to use for both personal and commercial projects. There are no licensing restrictions or usage limitations. Use it as often as you need for any type of project.

Question 10

Does trimming affect image quality?

Accepted Answer

No, trimming only removes transparent pixels from the edges. Your image quality, colors, and remaining pixels remain completely unchanged. It's a lossless operation that only affects the image dimensions.
