Should I use the homepage or a tool?

Use the homepage when you need a straightforward format change (for example DOCX to PDF or MP4 to WebM). Use a tool when the job is about size, dimensions, editing video, or archives.

Do tools require an account?

No. All listed tools work without signing in, the same as the main converter.

Where are file size limits listed?

Each tool page shows limits on the upload zone. Image and document limits differ from video and archive limits.

Can I convert format pairs directly?

Yes. Visit the Convert directory for dedicated pages like PDF to DOCX or HEIC to JPG with step-by-step guidance.

What is the difference between resize and compress?

Resize changes pixel dimensions. Compress keeps dimensions and reduces file size through encoding settings.

Can I upscale a small image?

You can, but upscaling cannot invent detail. Results may look soft; start from the largest source available.

Which formats are supported?

Common raster formats including JPG, PNG, WebP, AVIF, and TIFF within the image size limit.

Will aspect ratio be preserved?

Fit modes control whether the image is letterboxed, cropped to fill, or stretched to exact dimensions.

About this tool

Platforms and design systems often require precise widths and heights. Resizing scales the entire image to new pixel dimensions—unlike cropping, which removes parts of the frame. Use this when a spec sheet lists numbers, not percentages.

How to use

Upload your source image.
Enter target width and height in pixels.
Choose a fit mode (contain, cover, or stretch) appropriate for your layout.
Download the resized file.

File size limits

Resize to exact dimensions. Images up to 200MB.

Common use cases

Social media specs

Match Instagram, LinkedIn, or YouTube thumbnail dimensions without opening a desktop editor.

E-commerce listings

Normalise product photos to marketplace minimum and maximum sizes.

Documentation

Shrink screenshots for wikis and support articles while keeping text legible.

Tips

If you need to remove borders or focus on a subject, crop in an editor first, then resize to the final export dimensions so aspect ratio stays intentional.
