Compress Image Size In 3 Steps
Upload photos
Upload one or several images by dragging files directly from a folder to Watermarkly’s image compressor or click on "Select Images" and choose one of the following options: from your computer, Google Drive, Google Photos, Dropbox, or web page.
If you want to import images from either of the cloud storages, you will need to grant access to your account first.
Choose the quality you need
The photo compressor offers three options for compressing the size of an image:
- Better Quality – choose this option if preserving excellent quality is a priority for you.
- Smaller Size - go for this option if compressing your photos dramatically is your main goal.
- Specific File Size - this option is ideal if you need to compress images to a certain number of kilobytes and have more control over the final results of image compression.
Export your compressed images
Click on “Compress Images”. If you choose the Better Quality or Smaller Size option, you will see the size of your compressed images in bytes after the process is finished.
Download them to your device or a cloud storage account. Our image compressor does everything in its power to keep the quality of your compressed photos at the level of the originals yet reduce their size from megabytes to kilobytes.
Compress Image OnlineHow to compress an image with Watermarkly
You can compress photos with and without loss of quality. This solely depends on the type of compression. There are two of them – lossy and lossless. It’s also worth mentioning that one image format can support only one type of image compression, but not the other. Let’s take a closer look at them.
Lossy compression is supported by JPEG
When you compress JPEG, some redundant data is removed. This type of compression is called lossy because some loss of quality occurs no matter what. For this reason, if you apply really strong compression to your images, their quality will degrade drastically. But if you compress images the right way, you won’t see much of a difference between the original and the compressed copy. Lossy compression can reduce the file size of an image by a lot.
Lossy compression uses the imperfection of the human eye to its advantage. You may not know this, but people pay more attention to the contrast between brightness and darkness than to the contrast between colors and nuanced hues. The way lossy compression works is it gets rid of similar-looking colors and some finer details but doesn’t change bright and dark spots. For this reason, you won’t see much of a difference in quality.
Lossless compression is supported by PNG and GIF
There is no loss or degradation of quality in lossless image compression. When you compress photos this way, no redundant data is removed. The image is simply compressed; kind of like a zip-archive. Which is why, when lossless compression occurs, the file size of an image won’t be significantly reduced.
Lossless compression is a fully reversible process, which means that you can restore your compressed images to their initial state, which is impossible with lossy compression.
PNG is a format that is commonly used for digital graphics – logos, icons, images with a lot of text, etc. PNG images cannot be compressed to the same size as JPEGs – they will always be bigger.
GIF is used for files with animation. Even though it's a lossless format, GIFs are usually of more manageable size.
