How to use Cezar Image Tools
- Add one or more JPG, PNG or WebP files with the button or by dropping them into the upload area.
- Choose Compress, adjust quality and compare the preview and file sizes.
- In Resize, enter a width or height. The aspect ratio starts locked; percentage buttons use the current crop’s original dimensions.
- In Crop, choose a ratio and drag the selection or its corner. Rotate or flip the image as needed.
- In Convert, choose JPG, PNG or WebP. Check the transparency warning before choosing JPG.
- Select a thumbnail to edit that image. Apply to all copies shared settings; check each image before downloading the batch.
- Download the selected result or download all images in one ZIP. Reset restores the selected original; New task clears the session.
Reduce image file size without guessing
Large photographs can slow a website or exceed an email attachment limit. Compress JPG or WebP by lowering quality gradually, then inspect fine details in the preview. PNG compression works differently: lowering quality reduces colour precision while keeping the alpha channel. For logos or screenshots with fine text, start at 100% and compare. The tool reports the actual size and savings, including when an export is larger than the original.
Resize and crop images for a clear composition
Changing pixel dimensions often saves more space than aggressive compression. Resize an image proportionally for a product listing, a document or a smaller screen. Use 25%, 50% or 75% as a quick starting point. Cropping removes unwanted edges instead of stretching the picture. Square, landscape and portrait ratios help prepare consistent images, while rotation and flips let you correct the orientation. Check the final dimensions before saving.
Convert JPG, PNG and WebP in batches
Choose a format for the destination: JPG for photographs where transparency is unnecessary, PNG for transparent artwork or sharp graphics, and WebP for compact images supported by modern browsers. Convert JPG to PNG without expecting lost details to return; convert PNG to JPG only when a white background is acceptable. For multiple images, share quality, format and size settings, then download the results together as a ZIP with individual files.
Frequently asked questions
Are my images uploaded anywhere?
No. Processing and ZIP creation happen in your browser. No account is needed. Originals remain unchanged, and refreshing or starting a new task clears this editing session.
Why can the result be larger?
The original may already be well compressed. PNG, a higher quality setting or larger dimensions can increase the output size. Compare the actual result; try a smaller width, lower quality or WebP if appropriate.
Does conversion improve quality or preserve animation?
Conversion cannot recover lost details. JPG is lossy; PNG can preserve colours at 100%, and WebP supports transparency. Edited exports are still images, so animation and some metadata or colour profiles may not be preserved.
