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.

Which formats can I compress?

JPG, PNG, WebP, AVIF, and TIFF are supported up to the image size limit shown on the upload zone.

Will compression reduce image quality?

Lower quality settings trade visual fidelity for smaller files. Use higher quality for print or brand assets; lower for thumbnails and previews.

Is compression the same as resizing?

No. Compression keeps dimensions and reduces bytes through encoding. Use our resize tool when you need exact pixel width and height.

Do files leave my browser?

Image compression runs through our standard image pipeline. Check the guides page for details on client vs server processing.

About this tool

Oversized photos slow pages, bounce in inboxes, and waste mobile data. This compressor re-encodes common raster formats so you keep a predictable look while shrinking bytes—ideal before uploading to a CMS, newsletter, or marketplace.

Choose a quality level that matches your destination (web, print proof, or archive).

Tips

Start from the highest-quality source you have. Re-compressing the same lossy file repeatedly can introduce artefacts—archive the original before aggressive compression.
