How to use Image Compressor online
Compress images online by loading your files, choosing practical compression settings, and checking the output before download.
- 1
Add your file
Upload one or more JPG, PNG, WebP, or other browser-readable image files. Wait for the thumbnails to appear so you can confirm the right files are in the batch.
- 2
Adjust settings
Choose JPEG, PNG, or WebP output, set the quality level, and enter maximum width or height values when you need smaller dimensions as well as a smaller file size.
- 3
Export the result
Run compression, compare the new file size and preview, then download individual images or use Download All after the full batch looks ready for use.
Quality and size preview
Preview the compressed result beside the original file name and size so quality loss is easier to catch before export.
Local browser processing
Compression runs in the browser with canvas output, which keeps the workflow quick for normal web and document images.
JPEG, PNG, and WebP output
Pick the format that fits the job: JPEG for photos, PNG when you need that format, or WebP for modern web delivery.
Dimension limits
Maximum width and height controls let you downscale oversized camera images while preserving the original aspect ratio automatically.
Download controls
Download one compressed image for a quick fix or download every finished result after a full batch run.
Image Compressor privacy and processing
Image Compressor processes selected files in the browser session while keeping quality, dimensions, output format, preview, and download checks visible for review.
Processing Browser
Image Compressor uses your browser canvas to resize, re-encode, and preview each image before you download the smaller file.
Storage None
Selected images and compressed results stay in the current browser session. Save the downloads before refreshing or clearing the page.
Image Compressor account access
Image Compressor can be used without creating an account. Keep the page open until every compressed image you need has been downloaded.
Before You Use Image Compressor
Check the source image, target format, and final use case before you compress image files for production, handoff, or upload.
Privacy
Use only images you are allowed to process, especially when files include client work, unreleased product photos, IDs, or private screenshots.
Browser-side processing keeps the session local, but the compressed downloads still need to be stored and shared according to your own privacy rules.
Input Quality
Start with the cleanest available source. Already compressed screenshots and social media downloads can show artifacts faster than original camera files.
Strong compression can soften edges, text, and product details, so inspect logos, UI screenshots, and faces before using the result.
Output
Keep the original files until the compressed downloads open correctly and match the required size, format, and visual quality.
If a site or form needs a strict file size such as 100 KB or 1 MB, run a test download and adjust quality or dimensions until the file fits.
Limits
Image Compressor accepts browser-readable image files and processes them locally. Very large photos, long batches, or high-resolution exports can slow the active tab.
Compression speed depends on device memory, image dimensions, selected quality, and the number of images in the batch.
Questions about Image Compressor
What does Image Compressor do?
Image Compressor reduces image file size by re-encoding images in your browser. You can adjust quality, set maximum dimensions, choose JPEG, PNG, or WebP output, and download the compressed result.
Does compression change my original image files?
No. The tool creates new compressed downloads in the browser and leaves the original files on your device unchanged for comparison.
Which settings matter most when compressing images online?
Quality affects file size and visible detail, while max width and max height reduce pixel dimensions. For web images, test WebP and JPEG, then choose the smallest file that still looks clean.
Can I compress multiple images at once?
Yes. Add multiple image files, run compression once, review each preview, and download individual results or the whole finished set.
Why did my compressed image not get much smaller?
Some images are already optimized, and PNG files with flat graphics may not shrink much without changing dimensions or switching format. Try lower quality, smaller max dimensions, or WebP when the destination supports it.
