Why is my compressed image larger in Pixel Press?

Pixel Press creates a new JPEG or WebP; it does not guarantee a smaller file. If the result says LARGER, lower quality or reduce dimensions, then select Compress image again. Compare the new size and preview before downloading. Keep your original if none of the results meets your needs.

Open Pixel Press

Read the size comparison before saving

After selecting Compress image, read ORIGINAL, COMPRESSED and the percentage beneath SMALLER or LARGER. The app calculates that percentage from the original file?s bytes and the newly encoded result?s bytes. A LARGER result means processing completed, but the new file takes more space.

For example, if an original is 200 KB and the result is 250 KB, the result is 25% larger. That is an illustrative calculation, not a measured image test. Use the size panel to decide whether the output is useful rather than assuming the Compress image button guarantees savings.

Understand what the app creates

Pixel Press draws your image onto a canvas and asks the browser to encode a new file using the selected format and quality. It accepts JPEG, PNG and WebP input, but the output choices are JPEG and WebP. This creates one result from your settings; it does not keep trying settings until it reaches a smaller size.

The app explicitly allows a result to be larger than its source. It also removes original metadata through canvas re-encoding and does not preserve animation. Keep the source file if either matters to your workflow; a smaller byte count alone does not make the result a suitable replacement.

Lower quality and create a fresh result

Start by changing one setting so the next comparison is easy to interpret. If quality is 80%, for example, try 70% and select Compress image again. The slider runs from 10% to 100%. The number is an encoding setting, not a promised percentage reduction in file size.

Changing quality clears the previous result and disables Download image and the Compressed preview until you process again. Read the new size, switch between Original and Compressed, and inspect details you need to keep, such as lettering in a product label. If the preview is unsuitable, raise quality and process again.

Reduce dimensions when the destination allows it

If quality adjustments do not give you a useful result, consider whether the image needs all its original pixels. Change either Width or Height; Pixel Press calculates the other dimension from the original proportions, rounding to a whole pixel. It supports reducing dimensions, with no upscaling.

For example, a 2400 by 1600 source becomes 1200 by 800 when you enter a width of 1200. Use that only if those dimensions suit where the image will appear. Select Compress image again and check both the preview and file size. There is no target-byte-size control, so finding an acceptable result is a manual comparison.

Choose the format, then download deliberately

You can also compare JPEG and WebP by selecting a format and processing again. Check transparency before making that choice: JPEG fills transparent areas with white, while WebP supports transparency. A transparent logo that needs to sit over a colored background therefore needs more than a favorable size reading.

Pixel Press holds one current result rather than a gallery of attempts. Download a candidate before changing settings if you want to keep it for comparison. Download image requests a file with a -pixel-press suffix and a .jpg or .webp extension; your browser controls the save location. If every acceptable result is larger, keep the original instead.
