JPG, PNG, WebP and more · select several at onceHow to use
- Drag and drop your images, or click Choose images. You can select several at once.
- Set the quality. Leave it at 75% first, check the result, then adjust.
- For very large photos, set a maximum size such as 1920 px on the longest side, and choose JPG or WebP.
- Press Compress to see the new size of each image, then download them one by one or all together as a ZIP.
When to compress images
Upload forms for job applications, visas and government services often limit attachments to 1 MB or less. Smaller images make websites and online stores load faster, and they get past email attachment limits and messaging app caps. Modern phone cameras take photos more than 4,000 pixels wide, but 1,920 pixels is plenty for viewing on a screen or posting online.
Two ways to cut file size
Lower the quality: JPG and WebP let you choose a quality when saving. Lower quality removes fine color variations the eye rarely notices, which saves a lot of space. Going from 90% to 75% often cuts the file almost in half.
Reduce the dimensions: File size falls roughly in proportion to the number of pixels. Halving the longest side from 4,000 px to 2,000 px leaves only a quarter of the pixels. Combining both methods gives the biggest savings.
Recommended settings
| Use | Quality | Max size | Format |
|---|---|---|---|
| Forms with a 1 MB limit | 75% | 1920 px | JPG |
| Blogs and online stores | 75–80% | 1920 px | WebP or JPG |
| Email and messaging | 70% | 1280 px | JPG |
| Printing and archiving | 90% | Original | JPG |
JPG or WebP?
JPG opens in virtually every program and device, which makes it the safest choice for photos you send to other people or submit with forms. WebP, developed by Google, is typically 25–35% smaller than JPG at the same visual quality and also supports transparency, so it is a good fit for images on your own website.
Privacy
Your photos never leave your device. Re-saved images do not keep EXIF metadata such as GPS coordinates or the camera model. When the tool keeps an original file instead, that file still contains its original metadata. If you need to remove location data, check that the result was re-saved before sharing it.
Frequently asked questions
- How much smaller will my images get?
- A typical 3–8 MB phone photo usually drops to 300–800 KB at 75% quality with a 1920 px maximum size. Images that are already heavily compressed barely shrink; when the result is not smaller, the original is kept.
- Will the quality look worse?
- JPG and WebP compression removes detail your eyes are least likely to notice first, so at 70–80% quality most people cannot see a difference on screen. For screenshots with text or images you plan to print, use 85% or higher.
- Can I compress PNG files?
- Yes. PNG is lossless, so it cannot be shrunk much in its own format; the tool saves the result as JPG or WebP instead. Choose WebP to keep a transparent background. In JPG, transparent areas become white.
- Are my photos uploaded?
- No. Images are compressed in your browser and never sent to a server. Re-saved images lose EXIF metadata such as GPS location and camera details. If the tool keeps an original because the new file is not smaller, its metadata remains.
- Does it work with iPhone HEIC photos?
- Most browsers cannot open HEIC. On your iPhone, choose Settings > Camera > Formats > Most Compatible to save new photos as JPG. Photos are often converted to JPG automatically when you share or email them.
- How many images can I compress at once?
- There is no fixed limit, but images are processed one after another, so large batches take longer. On a phone, batches of a few dozen work best.
