Choose the dimensions needed for your destination first, then adjust quality. Repeated lossy re-encoding can reduce detail.
Troubleshooting
If WebP encoding is unavailable, choose JPG or PNG. JPG places transparent areas on white. Applying size in the guided editor preserves pixels in PNG history; use this tool’s Download button for its compression settings.

Before you use Resize & Compress
Can I enlarge a small photo?
No. This tool reduces dimensions or keeps the original size; it does not add detail or upscale.
Why does PNG have no quality slider?
PNG uses lossless encoding. Reduce dimensions or choose a lossy format when you need a smaller file.
Do compression settings carry into the final guided download?
Apply size & continue stores resized pixels. Download here to use this tool’s format and quality settings. The final guided download has its own format settings.
Which files can I use, and what can I download?
Choose a JPG, PNG, or WebP up to 30 MB and 40 megapixels. Download as JPG, PNG, or WebP when your browser supports encoding it. Your photo is processed in your browser.
