Compress before upload
When a website backend, form, CMS, or publishing platform limits image file size, compress the image first and check whether the visual result still works.

Why use local online image tools
Online image tools are best for clear, lightweight tasks: making images smaller, trimming extra edges, changing the output format, combining multiple images, or exporting the exact size a platform requires.
Browser-local processing can reduce upload steps for unpublished page screenshots, product photos, article images, social covers, extension store assets, and video thumbnails. Keep the original file, then check the final size, format, and clarity after export.
Online image tools FAQ
Common questions about online image processing, formats, dimensions, and privacy.
What is ImgsDIY?
ImgsDIY is an online image toolset for compressing images, cropping dimensions, converting formats, making collages, and creating platform-size assets. Choose a tool, upload an image, preview the result, and download it.
Are my images uploaded to a server?
Most image processing runs in the browser, so the source image does not need to be uploaded to a server by default. Browser performance and image size can affect speed, so keep your original file before processing.
Which image formats are supported?
Support varies by tool, but common input and output formats include JPG, PNG, and WebP. Some tools also offer AVIF output. Check the export settings on each tool page for the exact options.
When should I use platform size tools?
Use platform size tools when you are creating Chrome Web Store assets, an X header, an Open Graph share image, or a YouTube thumbnail. They start with the target canvas instead of asking you to type dimensions manually.
Will compression or conversion affect image quality?
It can. JPG, WebP, and AVIF usually trade some detail for a smaller file. PNG is often better for text, icons, and transparency. Preview the result before downloading the final image.
What is the difference between crop resize and preset sizes?
Crop resize is best when you already know the exact width and height for one image. Preset sizes are better when your target is a publishing scenario, such as Open Graph, X banner, or YouTube thumbnail.
