Choose the task, prepare the image
Online image tools handle specific tasks: reduce file size, change pixel dimensions, crop, replace a background or convert formats. Use the filters to find the tool you need; each page has its own settings and output checks.
Compress, resize, crop or convert?
| What do you need? | Tool & action | Check the result |
|---|---|---|
| A file is too large to send | Image Compressor Choose quality or a target file size per image. | Check KB/MB and important detail. Very low targets may not be achievable. |
| Need a specific width and height | Image Resizer Enter pixel dimensions; lock the ratio to preserve proportions. | Check output dimensions. Resizing does not guarantee a specific file size. |
| Need a different frame or fewer distractions | Image Cropper Choose a ratio or position the crop around the subject. | Anything outside the selection is removed. Check the subject before downloading. |
| The destination requires JPG, PNG or WebP | Image Format Converter Choose a format the destination accepts, then preview. | Check transparency and clarity. The converted file may be larger. |
| The image is too small or needs sharper detail | Image Upscaler / AI Image Sharpener Choose an enlargement factor or try AI 2× and compare. | A larger image does not guarantee recovery of lost detail; inspect text and faces. |
From the original to a publishable image
Product images with consistent backgrounds
Use Background Changer for white or custom backgrounds, position the subject, then resize or crop for the destination. Check hair, edges, shadows and product colors before using the composite.
Images that need a logo or watermark
Finish cropping and resizing first, add a text or logo watermark, then review every image to avoid covering important content. Use ZIP download where available and check a file after extracting it.
If the downloaded image is not what you expected
- Transparency becomes white
- JPG does not preserve transparency. Choose PNG or WebP in a tool that supports it, then open the downloaded file to check the background and edges.
- A GIF loses its animation
- Resizing, cropping or format conversion may create a still image. If you only need a smaller animated file, use Image Compressor with GIF-preserving output and check the downloaded file.
- An image will not open or processing stops
- Check formats and limits on the tool page. Try a smaller image, fewer files for a batch, or Image Format Converter if the source format is supported.
Check image data before sharing
Keep the original and read the processing notice before choosing a sensitive image. Compression, resizing and format conversion process image content in your browser; some AI tools need a network connection to download a model on first use.
To remove capture location or camera details, use Metadata & EXIF Remover and reopen the result in Metadata & EXIF Viewer. Do not assume a format change removes every sensitive field.
