How to Use Image Compressor and Resizer

  1. Add Your Images

    Drag JPG, PNG or WebP images onto the drop area, or select Choose images. You can add up to 20 images at a time, each up to 25 MB and 50 megapixels. HEIC, AVIF, GIF and animated images are not supported.

  2. Choose How Much to Compress

    Choose By quality and move the slider, or To a file size and pick 20, 50, 100 or 200 KB or enter your own size. For a file size, the tool lowers the quality, to no less than 40%, and then reduces the width and height if it has to.

  3. Resize and Pick a Format (Optional)

    Enter a width and height in pixels, or a percentage. The aspect ratio is kept by default, and images are not enlarged unless you allow it. Keep each image's format, or save them as JPG, PNG or WebP.

  4. Compress and Download

    Select Compress images. The images are processed in your browser, one after another, and each one shows its new size and dimensions. Download them one by one, or all together as a ZIP file.

Key Features

Compress to a Size in KB

Pick 20, 50, 100 or 200 KB or type your own size. The tool looks for the highest quality that fits, reduces the dimensions only if it must, and tells you plainly when a size could not be reached.

Resize by Pixels or Percentage

Enter a width, a height or both, or a percentage of the original size. The aspect ratio is kept by default, and smaller images are left at their size unless you choose Allow enlarging.

Convert Between JPG, PNG and WebP

Keep each image's format or convert it. PNG and WebP keep transparency; JPG has none, so transparent areas become white.

Processed in Your Browser

Your images are read, compressed and saved on your own device with your browser's built-in image encoders. They are not uploaded to ToolistHub's server.

Real Sizes, Before and After

Each image shows its file size and dimensions before and after, and a warning when the result is larger than the original or a size target was not met.

EXIF Metadata Removed

Saved images don't include EXIF metadata such as the GPS location, camera model or date taken. Photos are first turned upright according to their EXIF orientation, so they don't end up sideways.

Common Use Cases

Online Forms and Job Applications

When an application form or exam portal asks for a photo or signature under a size such as 50 KB or 100 KB, choose that size, compress the image and upload the result.

Email Attachments

Make phone photos smaller before you attach them, so more of them fit within your email provider's attachment limit.

Websites and Blogs

Resize photos to the width your pages show them at and save them as JPG or WebP, so visitors have less to download.

Many Photos at Once

Compress up to 20 photos with the same settings in one go and download them together in a ZIP file.

Tips & Best Practices

  • For a form with a size limit, use To a file size instead of guessing a quality: the tool checks the real file size for you.
  • Save photos as JPG or WebP. PNG is a lossless format, so a photo saved as PNG is usually much larger.
  • If a size target leaves an image too small or blurry, choose a slightly larger size if the form accepts it, or crop the photo first so there are fewer pixels to fit into the size.
  • Some upload forms accept only JPG or PNG, so check what a form takes before you save as WebP.
  • iPhones often save photos as HEIC, which this tool can't open: share or export them as JPG first.
  • The tool saves new copies with -compressed in the name and doesn't change your original files, so keep the originals if you may need full quality later.

Frequently Asked Questions

How do I compress an image to 50 KB?▼

Add the image, choose To a file size, select 50 KB and select Compress images. The tool lowers the quality, to no less than 40%, and if that is not enough it reduces the width and height until the file is at or under 50 KB (50,000 bytes). The result shows the final size, and says so plainly if 50 KB could not be reached.

Are my images uploaded to a server?▼

No. The Image Compressor works in your browser: your images are read, compressed and saved on your own device with your browser's built-in image encoders, and they are not uploaded to ToolistHub's server.

Which image formats can I compress?▼

JPG (JPEG), PNG and WebP. You can keep each image's format or save them as JPG, PNG or WebP. HEIC, AVIF and GIF files, and animated images, are not supported. On an iPhone, share or export a HEIC photo as JPG first.

How many images can I compress at once?▼

Up to 20 images at a time, each up to 25 MB, 50 megapixels and 16,383 pixels wide or tall. They are processed one after another in your browser to keep memory use down, so very large images can take a while, especially on phones.

Does compressing remove the location and other EXIF data?▼

Yes. The saved images don't include EXIF metadata, so details such as the GPS location, the camera model and the date taken are not copied into them. Photos are first turned upright according to their EXIF orientation. Your original files are not changed.

Why doesn't my PNG get smaller?▼

PNG is a lossless format, so the quality setting doesn't change it, and a PNG saved again can even be larger than the original. To make it smaller, reduce its width and height, or convert it to JPG or WebP. Each result shows its real file size, with a warning when it is larger than the original.

What is lost when I compress an image?▼

At a lower quality, JPG and WebP images lose fine detail, which can show as blur or blocky patches. The saved images don't include EXIF metadata, and they are saved with 8 bits per colour channel, so a 16-bit PNG loses its extra precision. JPG has no transparency. Animated images are refused rather than cut down to one frame. Your original files are not changed.

Will resizing stretch or enlarge my images?▼

Not unless you choose to. The aspect ratio is kept by default, so the image fits inside the width and height you enter; turning off Keep aspect ratio sets each side on its own. Images smaller than that size are left as they are unless you turn on Allow enlarging, and a percentage can't make an image larger.

What happens to transparent backgrounds?▼

PNG and WebP keep transparency. JPG has no transparency, so transparent areas become white when an image is saved as JPG.

Is the Image Compressor free?▼

Yes. It is free, needs no account and adds no watermark. Because it runs in your browser, there is no hourly limit on how often you can use it.
