WebP Compressor
Compress WebP images online without resizing dimensions.
PRACTICAL WORKFLOW NOTES
Tune an Already-Efficient WebP for a Smaller Delivery Budget
WebP Compressor is for images that are already in a modern web format but still exceed the size budget of a page, form, message, or content system. Because WebP may already be strongly compressed, a second encoding pass can have diminishing returns. The current tool keeps pixel dimensions unchanged and lets you choose how much additional compression is acceptable rather than pretending every WebP can be made dramatically smaller without a visual tradeoff.
Low, Medium, and High compression increase the pressure toward a smaller output. Inspect areas with fine texture, gradients, small type, and sharp product edges when choosing a stronger level. No compression is intended for cases where the source can remain unchanged under the selected output and target settings. Target KB can be entered as a goal, but complex images may remain above that value when resizing is not allowed.
Keep WebP when the destination supports it and modern web delivery is the priority. Choose JPG when a recipient requires broader legacy compatibility, or PNG only when that format is specifically needed and its lossless behavior makes sense for the image. Changing format can alter file size significantly, so the best choice depends on the receiving workflow rather than on the source extension alone.
Re-encoding occurs in the browser. Use the 100KB or 200KB target tools when an external limit should be preselected. Use Image Resizer if reducing width and height is permitted, especially when an already-efficient WebP cannot meet the required size through compression alone.
How to Use WebP Compressor
Follow the workflow below and review the result before downloading.
Add images
Upload WebP files.
Choose output format
Keep Same as original or choose JPG, WebP, or PNG.
Choose compression and optional Target KB
Use No, Low, Medium, or High compression. Enter Target KB only when you want the compressor to aim toward a specific file size.
Compress in the browser
The selected image is re-encoded without a dimension resize.
Download and compare
Check the file size and visual quality, then download individual results or a ZIP.
What the Compression Controls Actually Change
File-size reduction comes from image encoding choices. The current compressor does not resize the image canvas.
No compression can keep the original
No compression keeps the original file only when the output format, size settings, and Target KB are unchanged.
Low, Medium, and High compression
Stronger lossy compression favors a smaller file with a greater chance of visible detail loss.
Width and height stay the same
The compressor does not reduce pixel dimensions in the current workflow.
Choose a different output format
Use JPG, WebP, or PNG output when the destination format matters as much as file size.
PNG needs special expectations
Lossless PNG output may not shrink. For PNG sources using Same as original with active compression, the engine may choose WebP for practical reduction.
Batch results
Process multiple files and download outputs individually or together as a ZIP.

PRIVACY & RESPONSIBLE USE
Image Compression Runs in Your Browser
The current compressor reads and re-encodes selected image files on your device.
See File Security & Processing and the Privacy Policy for broader site-level details.
Inspect important detail
Lossy compression can affect small text, edges, gradients, and fine image detail.
File size depends on image content
Two images with the same dimensions and quality setting can compress to very different sizes.
Use authorized images
Compression does not change copyright or licensing.

COMMON QUESTIONS
Frequently Asked Questions
Can I use WebP Compressor online for free?
Yes. The current compressor is free to use and does not require an account.
Does image compression change the dimensions?
No. The current compressor keeps the source width and height unchanged.
What do Low, Medium, and High compression mean?
They progressively reduce lossy encoding quality to favor smaller files. Stronger compression can make image artifacts more visible.
Can I choose a different output format?
Yes. The output options include Same as original, JPG, WebP, and PNG.
Can I compress several files at once?
Yes. Add multiple supported images and download results individually or as a ZIP.
What does Target KB optional do?
It lets you enter a file-size goal in kilobytes. The compressor can aim toward that value, but the exact result still depends on the image content, output format, and compression setting.
Are images uploaded to a server for compression?
The current image-compression workflow runs in your browser.
