About this Image Compressor tool
The Image Compressor reduces an image's file size while keeping it looking good — typically 50–90% smaller for photos, depending on the quality level you pick. The image stays in its original format and dimensions; the tool re-encodes it more efficiently and lets you trade a little (usually invisible) quality for a lot of size. Use it when an upload form rejects your file, an email attachment is too heavy, or a web page loads slowly because of image weight. Compression is the single biggest lever for page speed: a 4 MB camera photo compressed to 400 KB looks identical on screen and loads ten times faster.
How to use Image Compressor
- Open the tool and add your file, text or values.
- Review the available options such as page range, output format, quality, password or language.
- Start the process and keep the browser window open until it finishes.
- Download the result and continue with a related tool if needed.
Useful tips
- For scanned PDFs, tools with OCR support run text recognition automatically where possible.
- For large files, use compression tools before sharing by email or uploading to portals.
- For best results, upload clean files with the correct extension and avoid corrupted documents.
Compress, resize or convert — which do you need?
Compress (this tool) when the pixel dimensions are fine but the file is too heavy — the usual case for uploads and email.
Convert to another format when the format itself is the problem: PNG photos should usually become JPG (PNG to JPG), and web images become WebP (WebP Converter) for the smallest sizes.
Both at once: converting a PNG photo to JPG and then compressing it gives the largest total reduction.
Frequently asked questions
How much smaller will my image get?
Photos typically shrink 50–90% depending on the quality setting and how compressed the source already was. Screenshots and graphics compress less dramatically than photos.
Will I see the quality difference?
At moderate compression, almost never — screen viewing hides far more than print. Heavy compression eventually shows as softness and blocky artifacts, most visibly on sharp edges and text.
Does compression change the image dimensions?
No. Width and height in pixels stay the same; only the file size drops. The image is re-encoded, not resized.
Which formats can be compressed?
JPG, PNG and WebP. The output stays in the same format as the input, so nothing else in your workflow changes.
What quality setting should I choose?
For web and email, a medium-high setting is the sweet spot — big savings, invisible loss. Use the highest setting for images that will be printed or edited again.
Is the compressor free?
Yes — free, no account, no watermark, files cleaned from temporary storage automatically.
