1. Image Compressor
The Image Compressor reduces file sizes by applying lossy or lossless compression algorithms. Upload JPEG, PNG, WebP, GIF, or BMP files, choose a quality level, and download the compressed output. Batch processing allows you to compress multiple images simultaneously.
When to use it: Before uploading images to a website (to improve Core Web Vitals and page speed), before emailing photos (to reduce attachment size), or whenever you need to reduce storage consumption without noticeable quality loss.
Typical compression ratios: JPEG photos can often be reduced by 40–70%. PNG screenshots and graphics can be reduced by 20–40% through lossless optimisation, or much more if converted to JPEG or WebP.

2. Image Resizer
The Image Resizer changes the pixel dimensions of images — scaling them up or down. Enter a target width and the height calculates automatically with the aspect ratio locked, or enter both dimensions independently for specific size requirements.
When to use it: When preparing images for specific display sizes (website hero images, thumbnails, social media), reducing large camera files before web upload, creating standard-sized product images for e-commerce, or preparing images for print at specific DPI requirements.
Key feature: Batch resize allows standardising multiple images to the same dimensions — essential for product catalogs, photo galleries, and image grids where consistent sizes are required.

3. Image Cropper
The Image Cropper lets you select and keep a specific area of an image, discarding the rest. Use free-form cropping for custom selections, or choose from aspect ratio presets (1:1, 16:9, 4:3, 4:5, 9:16, and more) for platform-specific requirements.
When to use it: To improve image composition, remove distracting background elements, change aspect ratio for a specific platform, or extract a specific part of a larger image (such as a detail from a product photo).
The rule of thirds grid overlay helps you apply photographic composition principles while cropping, guiding you to position subjects at the intersection points of the grid rather than the centre.

4. Image Format Converter
The Image Format Converter converts images between JPEG, PNG, WebP, BMP, GIF, and TIFF. Select input files and the target output format, and the tool handles the conversion with your chosen quality settings.
When to use it: Converting website images to WebP for better performance, converting BMP legacy files to modern formats, converting JPEG to PNG when you need a lossless source for further editing, or converting PNG to JPEG to reduce file size for sharing.
Batch support: Convert multiple files to the same target format simultaneously and download as a ZIP archive.

5. Background Remover
The Background Remover uses AI semantic segmentation to identify the foreground subject in a photo and remove the background, producing a transparent PNG output. It works on portraits, product photos, pets, logos, and more.
When to use it: Creating transparent product images for e-commerce (white background or transparent), preparing headshots for professional profiles, creating design assets, compositing images, or any situation where you need to isolate a subject from its background.
Accuracy: Excellent for portraits and products on simple backgrounds. Very good for moderately complex backgrounds. Fine hair and transparent objects remain the hardest edge cases. See our detailed comparison: Best Free Background Remover Tools Compared.

6. HEIC to JPG Converter
The HEIC to JPG Converter converts HEIC and HEIF image files (the default format for iPhone photos) to universally compatible JPEG. It handles single files and batches, converting at full resolution with your chosen quality setting.
When to use it: Whenever you need to share iPhone photos with Windows or Android users, upload photos to websites that don't accept HEIC, edit photos in software that doesn't support HEIC, or send photos to print services that require JPEG.
Privacy: Files are not stored on servers after processing. The conversion happens quickly and the converted JPEG is available for immediate download.

7. Image to Text (OCR)
The OCR tool (Optical Character Recognition) extracts text from images, scanned documents, and photographs of printed or handwritten text. Upload an image and receive the extracted text that can be copied, edited, and used anywhere.
When to use it: Digitising printed documents, books, or articles; extracting text from screenshots; converting scanned invoices or contracts to editable text; reading menu photos or signs; extracting data from product packaging photos; and processing photographed forms or certificates.
Accuracy: Excellent for clearly printed text with good contrast. Good for most typed documents and clear photographs. Handwriting recognition accuracy varies significantly depending on the clarity and style of the writing.
Choosing the Right Tool for Your Task
Here is a quick decision guide:
- Image is too large for web upload or slow to load? → Use the Image Compressor.
- Image is the wrong dimensions for a platform or use case? → Use the Image Resizer.
- Image has unwanted content at the edges or needs a specific aspect ratio? → Use the Image Cropper.
- Image is in the wrong file format? → Use the Image Converter.
- Need to remove the background from a product photo or portrait? → Use the Background Remover.
- Have HEIC files from iPhone that won't open on other devices? → Use the HEIC to JPG Converter.
- Need to extract text from a photo or scanned document? → Use the OCR tool.
