How to Compress Images Online

Follow these four simple steps to make your images smaller in seconds.

Add your images. Click Choose Images or drag and drop JPG, PNG or WebP files into the upload box. To use an image that is already online, click From URL, paste its direct link and press Add images.
Pick your settings. Set the quality (70-80% is recommended), choose JPEG, WebP or Keep original, and optionally set a maximum width to resize large photos.
Check the result. Each image shows its original size, its new size and how much space you saved.
Download. Click Download next to an image, or Download all to save every compressed file.

Tips for the best results

Use WebP for the smallest files on websites. It also keeps transparency.
Use JPEG when you need maximum compatibility, for example for email or older software.
Choose Keep original if you must stay in the same format as the source file.
Resize very large photos (for example 4000 px wide) to 1600-2000 px before publishing them on a website.
Keep your original files. Compression removes detail permanently.

Using From URL

The link must point directly to an image file (it usually ends in .jpg, .png or .webp) and the image must be publicly available. Links to web pages, private files or images that need a login cannot be loaded.

Common questions

Is Image Compress really free?

Yes. The image compressor is completely free, with no signup, no watermark and no daily limit.

Are my images uploaded to your server?

No. Images you choose from your device are compressed inside your own browser, so they never leave your computer or phone. When you use the From URL option, the image is only fetched temporarily so it can be loaded into the tool, and it is not stored.

Which image formats are supported?

You can add JPG/JPEG, PNG and WebP images. You can save the result as JPEG, WebP, or keep the original format.

Will compression reduce my image quality?

Compression is lossy, so a small amount of detail is removed. A quality setting between 70 and 80 usually gives a much smaller file with no visible difference.

Why did my PNG not get much smaller?

PNG is a lossless format, so it does not shrink much by quality settings alone. Choose WebP or JPEG as the output format to get far smaller files.

Can I compress an image from a link?

Yes. Click From URL, paste a direct link to a JPG, PNG or WebP image and press Add images. The link must point straight to an image file, not to a web page, and the image must be publicly accessible.
