What does Image Compressor do?
Compress images with either direct quality controls or a real target-size search. Tubelexity measures every encoded Blob, uses bounded quality iterations, and can reduce dimensions when you permit it. Results show actual bytes, savings, dimensions and the quality used instead of promising an exact size that an encoder may not produce.
How to use Image Compressor
- 1Add one or more supported images.
- 2Choose quality mode or a target such as 100 KB, 1 MB or a custom size.
- 3Choose output format and whether resizing is allowed.
- 4Compress, inspect the measured before-and-after result, and download.
Supported inputs and outputs
Inputs
JPG / JPEG, PNG, WebP, AVIF when the browser can decode it
Outputs
JPG / JPEG, PNG, WebP
Practical uses
- Meeting a 100 KB form limit
- Preparing a thumbnail below a file-size limit
- Reducing website image transfer size
- Compressing a batch before sharing
Browser and media limitations
- Target size is approximate because encoded sizes are discrete and content-dependent.
- PNG Canvas encoding does not expose a useful JPEG-style quality control.
- Tiny targets can be impossible without resizing or a format change.
- Large images and batches can exceed browser memory.
How local processing works
The image is decoded and rendered with browser image and Canvas APIs in this tab. Tubelexity does not upload the source or output to a processing server.
Frequently asked questions
How do I compress an image?
Add an image, choose quality or target-size mode, select the output format, and compress. Tubelexity reports the actual result size.
How do I compress an image to 100 KB?
Choose Target file size and 100 KB. The bounded encoder searches measured quality levels and can reduce dimensions if you enable resizing.
Can I compress an image to 1 MB?
Yes. Choose the 1 MB preset, but the final result may be slightly below or above the target depending on the format and image complexity.
Does image compression reduce quality?
Lossy JPEG and WebP compression can reduce detail. Resizing also removes pixels. PNG output is lossless at its output dimensions.
Is my image uploaded?
No. Decoding, resizing, encoding and byte measurement happen locally in the browser.
