Your results
Results are measured from the actual generated files. Some formats or images may become larger after re-encoding. Compare image quality before using the output.
Free Online Image Compressor
Compress JPG, PNG, WebP and supported AVIF images in seconds. Reduce image file size, set a target size in KB or MB, and preview your results before downloading. Your images are processed in your browser with FastTL.
Compress Your Images
Upload your images, choose your compression settings, and compare the results before saving your files.
Reduce Image File Size
Make images smaller for websites, online forms, email attachments, and everyday sharing. Actual savings depend on the original image and selected settings.
Target KB or MB Size
Try to reach a preferred file size, such as 100KB, 200KB, or 1MB. Results can vary, so check the final file size before using the image.
Batch Image Compression
Process multiple images in one session instead of repeating the same steps for every file. Large batches may require more memory and processing time.
Before-and-After Preview
Compare the original and compressed versions before downloading. Review both image appearance and file size to decide whether the result meets your needs.
Multiple Image Formats
Work with JPG, PNG, WebP, and AVIF where your browser supports the required format. Format support and output quality can differ between browsers.
Privacy-Focused Processing
Image processing takes place in your browser rather than uploading image files to the FastTL server through this tool. Your browser and device still handle the selected files.

Download the finished files and verify that they meet your website, upload, or sharing requirements.
How to Reduce Image Size Without Noticeable Quality Loss
The best compression settings depend on the image. Photographs, screenshots, logos, and transparent graphics behave differently. Use these tips to find a suitable balance between file size and visual quality.
- For website photos: Try JPG or WebP with a moderate quality setting and inspect fine details.
- For logos and transparent graphics: Keep PNG when transparency or sharp edges are important, or test WebP if your workflow supports it.
- For strict upload limits: Aim below the maximum allowed file size to leave a small safety margin.
- For very large images: Reduce the pixel dimensions if the original resolution is larger than needed.
- For important originals: Keep a backup before replacing the original with a compressed copy.
Note: Lossy compression may reduce image quality. Lossless compression preserves image data but may provide smaller file-size savings. Re-encoding an image does not guarantee a smaller file.

Frequently Asked Questions
Is FastTL Image Compressor free to use?
This tool is provided as a free online image-compression utility. Check the current FastTL page for any usage limits or changes to availability.
Can I compress an image to 100KB?
You can try setting a target of 100KB if that option is available in the tool. Reaching the exact size is not guaranteed because the result depends on the original image, its dimensions, format, and compression settings.
Can I compress JPG images without losing quality?
Lossless methods can preserve image data, but they may offer limited savings. Lossy JPG compression can reduce file size more substantially, although some visual information may be lost. Always compare the output before downloading.
Can PNG images be compressed without losing quality?
Lossless PNG optimization can preserve the original pixels, but the amount of size reduction varies. Re-encoding or converting the image may not produce a smaller file, so check the actual output size.
Are my images uploaded to the FastTL server?
The FastTL Image Compressor described here processes selected images in your browser. The image-processing workflow does not need to upload the image files to the FastTL server. Normal website requests and browser behavior may still involve network activity.
Does the tool support WebP and AVIF?
WebP and AVIF support depends on the browser’s image decoding and encoding capabilities. AVIF output may not be available in every browser or device.
Can I compress multiple images at once?
Yes, the tool supports batch processing within its configured file-count and file-size limits. Processing many large images can use significant device memory.
Will compression always reduce the file size?
No. Some images are already optimized, and certain formats or settings can produce a file that is the same size or larger. Compare the original and output sizes before choosing a result.
Make Your Images Easier to Share
Start with your image, choose suitable settings, and compare the final result. FastTL makes everyday image compression simple and accessible in your browser.
