About the Compress Image
Tezmy's Image Compressor makes photos and images much smaller while keeping them looking sharp: perfect for email attachments, websites, online forms with size limits and saving space on your phone. Adjust the quality slider to balance size and sharpness, optionally shrink very large photos, and choose to keep the format or switch to modern WebP. Compress many images at once and download them one by one or as a ZIP. Everything happens in your browser, so your photos are never uploaded.

How to compress a photo to 200 KB, 100 KB or 50 KB
Many job, exam and government websites only accept photos under a size limit. The size of each compressed image is shown right away, so you can adjust until it fits:
- Start with quality around 70%. Most phone photos drop well under 500 KB.
- For 200 KB or less, also choose Max 1920 px or Max 1280 px.
- For 100 KB or 50 KB, choose Max 800 px and lower the quality to 50–60%.
- If a form also needs exact pixel dimensions, like 600 × 600, set them first with Image Resizer, then compress.
JPG, PNG or WebP: which should you use?
Auto keeps photos as JPG and saves other images as WebP. If a website only accepts JPG, choose JPG. To change formats without compressing, use Image Converter.
- JPG: best for photos. Small files and supported everywhere.
- PNG: best for logos, screenshots and images with transparent backgrounds, but files are large.
- WebP: a modern format that is usually much smaller than both, with transparency support. Great for websites; a few older apps and upload forms still don't accept it.
Why compress images?
Photos from modern phones are often 3 to 8 MB each. Compressing them makes emails send faster, keeps you under upload limits, saves storage on your phone and makes websites load much quicker, which also helps them rank better on Google. At 60–80% quality the difference is very hard to see, but the file can be a fraction of the size.
Compress many images at once
Add as many images as you like. Each one is compressed on your own device, with its old and new size shown, and you can download them one by one or all together as a ZIP. Nothing is uploaded, which also makes it fast on a slow connection. When the file type is the problem, try JPG to PDF to send it as a document, and Crop Image to remove edges you do not need.

Frequently asked questions
Can I compress an image to an exact size like 50 KB?
Yes. Choose By file size (KB) and type the limit. Each picture is saved as a JPG at the highest quality that stays under it, and made smaller in pixels only if lowering the quality isn't enough.
How much smaller will my images get?
Typical phone photos shrink by 60–90% at 70% quality, especially when resized to 1920 px. Images that are already heavily compressed may only shrink a little.
Will compressing reduce the quality?
Slightly, but at 60–80% the difference is very hard to see. Use the slider to find the balance you like and compare the file sizes shown.
How do I compress an image to a specific size in KB?
Lower the quality and, if needed, choose a smaller maximum size until the size shown next to your image is under your limit, for example 200 KB for a form upload.
What does Auto format do?
Auto keeps JPG photos as JPG. PNG and other images are saved as WebP, a modern format that supports transparency and is usually much smaller than PNG.
Are my photos uploaded to a server?
No. Compression happens entirely in your browser. Your images never leave your device.
Can I compress images on my phone?
Yes. Open this page in Safari or Chrome, tap Select images and choose photos from your gallery. The smaller images are saved to your downloads.
Does compressing remove transparency?
Saving as JPG replaces transparent areas with white. Keep transparency by choosing PNG or WebP (Auto does this for PNG images).
Is there a limit on how many images I can compress?
No. Add as many as you like. Very large batches may take a little longer on older phones.
