About image compression
Web forms reject photos over 200 KB, emails choke on 8 MB attachments, and slow sites lose visitors — image size matters constantly. This compressor re-encodes JPG, PNG and WebP images at the quality you choose, showing every result with its exact savings so you can judge with your own eyes. Batches are welcome, and nothing is uploaded anywhere.
How to compress images
- Add one image or a whole batch.
- Set the quality slider — 70–80% is usually visually identical to the original at a fraction of the size.
- Choose JPEG output for maximum compatibility or WebP for the smallest files.
- Press Compress, review the before/after sizes, and download individually or as a ZIP.
Tips for smaller images
- Compressing an already-compressed image saves little — start from the original when you can.
- If the image is also larger in pixels than needed, resize it first; fewer pixels beat lower quality every time.
- PNG screenshots with photos in them shrink dramatically when converted to JPEG or WebP.
- For documents made of photos, compress the images before building a PDF with JPG to PDF.
Frequently asked questions
What quality setting should I use?
70–80% is the sweet spot — files shrink dramatically while looking identical to the original at normal viewing sizes. Go lower only when a strict upload limit forces it.
JPEG or WebP output?
WebP produces the smallest files and every modern browser supports it. Choose JPEG when the image goes somewhere older — government portals, email clients or print shops can be picky.
Can I compress many photos at once?
Yes — add a whole batch, compress in one click, and download the results individually or as a single ZIP.
Why did my image get bigger?
It was already compressed harder than your chosen quality. The tool shows a warning pill on any image that didn't shrink so you can keep the original instead.
