Image compressor
Make JPG, PNG, WebP and HEIC files smaller. Up to 20 images at once.
Advanced settings
Saves preferences only, never images. Uncheck to forget. Permission to resize for a target is requested each visit.Original format and dimensions by default. Resize only when you choose.

How to compress an image to 200 KB
- Choose a JPG, JPEG, PNG, or WebP image. Your file stays in your browser.
- Select the 200 KB preset under Target file size. You can also choose 500 KB, 1 MB, or enter a custom limit.
- Click Compress, then check the final file size and use Compare to inspect the image before downloading.
For example, a form with a 200 KB upload limit needs a result of 200,000 bytes or less. Toolkitta checks the actual output size; a target is not a guarantee. Detailed photos or lossless PNG images may need a larger limit or smaller dimensions.
If you see “Target not reached,” try the smaller-dimensions option only if your destination permits resizing. Check any minimum width and height requirements too. Original dimensions and format are kept unless you choose otherwise.
Useful details
Are my images uploaded or stored?
No. Compression and comparison happen in your browser, and your image files are not uploaded to Toolkitta. Keep this tab open until you download your results; closing or reloading it clears the current batch. Website hosting and performance measurement are described in our Privacy notice.
Which formats and file sizes are supported?
Add JPG (.jpg or .jpeg), PNG, WebP, HEIC/HEIF, AVIF, GIF, BMP, SVG, ICO or TIFF images by choosing files, dragging them in, or pasting an image with Ctrl+V / ⌘V while you are not typing in a field. You can add up to 20 images, 20 MB per file, and 100 MB per batch. Images must be no more than 40 megapixels or 16,384 pixels on either side. The browser can only write JPG, PNG and WebP, so with “Original format” a HEIC, AVIF, GIF, BMP, SVG or ICO file is saved as JPG (or PNG when it has transparency) and the row says so. Animated GIF, WebP and PNG keep their first frame only. Smaller PNG mode supports output up to 8 megapixels; JPEG images above 16 megapixels use the faster encoder to limit memory use.
Which output format should I choose?
Keep original format is the safest starting point. JPEG is useful for photos and broad compatibility. PNG keeps transparency and offers lossless compression for graphics and screenshots. WebP can be a smaller option for websites and supports transparency; check that your destination accepts it. When converting to JPEG, transparent areas use the background color you select in Advanced settings.
Does compression change image quality?
JPEG and WebP use lossy compression, so some detail can change. PNG is lossless by default at unchanged dimensions. Smaller PNG mode reduces the image to up to 256 colors and may change gradients or transparent edges. Resizing also changes pixels. Use Compare and zoom in before downloading. JPEG’s Smaller file option takes longer than Faster processing.
Can I compress to a specific KB size?
Choose Target size and enter your limit per image. Toolkitta searches for a result at or below that limit, but some targets cannot be reached. Original dimensions are kept unless you set a maximum size or explicitly allow smaller dimensions. If the target is missed, you can download the result, raise the limit, or try the resize option. Format never changes automatically. KB here means 1,000 bytes.
Can I resize, convert, or adjust just one image?
Advanced settings apply to the batch. Choose an output format or set a maximum width and height; resizing keeps proportions and never enlarges an image. After compression, open Compare → Adjust this image to change only that image’s quality or PNG compression mode. Each adjustment starts from the original file. Changing batch settings clears previous results and individual adjustments.
How do I compare and download my results?
Open Compare beside a completed image. Use Split, Original, or Result view, then choose Fit, 100%, or 200% zoom. Drag the divider or use its arrow keys; drag a zoomed image to inspect it. Resized results are aligned with the original for comparison. Download images individually, or use Download ZIP when two or more are ready. Cancel stops processing and keeps completed results.
Why is a file unchanged, and what happens to metadata?
Already-small images may not benefit from another compression pass. If the format and dimensions are unchanged and the original is smaller, Toolkitta keeps the original. Re-encoded images lose embedded metadata; untouched originals retain it, and lossless PNG optimization may retain metadata. This tool is not a guaranteed metadata remover. Check the note on each result.
