Compress Image Online
How it works
Choose your file, review the selected list, then start the tool. The browser sends the file to the processing API and returns a downloadable result.
Image compression depends on the input format. JPG, PNG, WebP, GIF, SVG, and AVIF files can have different size savings because each format stores pixels or vector data differently.
The result uses the shown output filename as a fallback when the server does not provide a specific download name. compressed-images.zip
File limits
Image files. Up to 20 files, 50 MB total.
The upload area checks file type, file count, and total size before processing so unsupported files can be corrected early.
For best results, crop empty background and resize very large photos before upload. Compressing an oversized image without resizing can still leave a file bigger than a form or CMS expects.
Privacy and file handling
Files are used only for the requested PDF task and are removed from temporary storage after processing.
Images can include personal details, documents, or background information. Crop unrelated areas and upload only files you are allowed to process online.
Output quality
The tool is tuned for practical everyday documents. Very complex layouts, image-heavy PDFs, or scanned pages can affect the final result.
Review small text, product labels, QR codes, faces, and fine lines after download. These details reveal whether compression was too strong for the image's purpose.
Reduce common image file sizes for upload, email, and sharing.
Common uses
- Preparing files for email, upload portals, or shared folders.
- Organizing document pages before sending them to clients, schools, or internal teams.
- Finishing small document changes on a phone, tablet, or desktop browser.
- Reducing product photos, screenshots, scans, and web graphics before uploading them to a website or form.
- Preparing image attachments that load faster in email, chat, and document workflows.
Troubleshooting
- If processing fails, check that the file is not password-protected or corrupted.
- If the upload is rejected, reduce the file size or split the job into smaller batches.
- If the output is not what you expected, try a cleaner source file with standard page sizes.
- If an image does not shrink much, it may already be compressed or may use a format that stores the content efficiently.
- If text becomes unclear, start from the original image and reduce dimensions or quality less aggressively.
