Choose the right image tool for the job
Image optimization is usually a sequence rather than one action. Start with the highest-quality original available, choose the right dimensions and composition, then select a delivery format and compression level that match where the image will be used.
Combine photos into one image
Use the Photo Collage & Image CombinerBatch Image Watermark for grids, side-by-side comparisons and photo strips. Adjust each photo’s crop, add captions and download PNG, JPEG or supported WebP.
Convert image formats
Use the Image Converter when compatibility or file format is the main problem. It supports common web formats and specialist inputs such as HEIC/HEIF and AVIF, with output choices detected from the production image engine.
Reduce image file size
Use Image Compressor when an image is already in the right format and dimensions but is too large for a webpage, email or upload limit.
Resize or crop an image
Resize Image changes pixel dimensions. Crop Image changes composition by removing pixels around the edges. When you need both, crop first and resize the final composition afterward.
Remove a background or create a PDF
The Background Remover uses browser-based AI to create a transparent PNG without a paid background-removal service. Image to PDF combines supported image files into one PDF locally in your browser.
Popular image conversion shortcuts
For common format changes, open a preselected converter: JPG to PNG, PNG to JPG, JPG to WebP, WebP to JPG, HEIC to JPG or AVIF to PNG.
Frequently asked questions
Which image tool should I use to make a website image smaller?
Resize it to the pixel dimensions actually needed, then compress it. If your website supports modern formats, converting a suitable image to WebP can also reduce delivery size.
Can I convert HEIC photos from an iPhone?
Yes. The Image Converter supports HEIC/HEIF inputs and includes a browser decoding fallback, with additional server conversion support depending on installed codecs.
Which tools keep my images in the browser?
Image compression, resizing, cropping, image-to-PDF and AI background removal are designed to run locally for supported formats. The full multi-format converter can use server processing for advanced codecs.
Does converting an image improve its quality?
No. Changing format can improve compatibility or file size, but it cannot recreate image detail that is missing from the source.
