Free Online Image Resizer – Resize Any Image Instantly

An image resizer is a tool that changes the pixel dimensions of a digital image. Whether you need to resize a photo for social media, reduce an image for email, or prepare graphics for a website, the Affivance image resizer handles it all directly in your browser.

How to Resize an Image Online

1. Upload your image using the upload button or drag and drop.
2. Enter your desired width and height, or use the percentage option.
3. Toggle aspect ratio lock to maintain proportions automatically.
4. Choose your output format (JPG, PNG, or WebP) and quality.
5. Click "Resize Image" and download the result.

Understanding Image Dimensions and Aspect Ratio

Image dimensions are measured in pixels (width × height). The aspect ratio is the proportional relationship between width and height. For example, a 1920×1080 image has a 16:9 aspect ratio. When you resize an image with the aspect ratio locked, changing one dimension automatically adjusts the other to prevent distortion.

Supported Formats

This image resizer supports JPG, PNG, and WebP files. You can resize a JPG for web use, resize a PNG while preserving quality, or resize a WebP image for maximum compression. The output format is selectable, so you can also convert between formats during the resize process.

Why Use a Browser-Based Image Resizer?

Browser-based image resizing means your files never leave your device. There is no server upload, no account required, and no software to install. The Affivance image resizer uses your browser's built-in Canvas API to perform the resize operation locally, ensuring complete privacy and fast processing.

WebP to JPG Converter – Convert WebP Images to JPEG Online

WebP is a modern image format developed by Google that offers excellent compression. However, not all applications, devices, and platforms support WebP files. Converting WebP to JPG ensures maximum compatibility across all software, operating systems, and websites.

What Is WebP and Why Convert It?

WebP provides both lossy and lossless compression, often producing smaller file sizes than JPG or PNG. While web browsers widely support WebP, many image editors, older devices, and certain platforms do not. Converting WebP to JPG solves these compatibility issues while maintaining good visual quality.

How to Convert WebP to JPG

1. Upload your WebP file using the upload button or drag and drop.
2. Adjust the JPG quality slider to balance file size and image quality.
3. Click "Convert to JPG" and wait for processing.
4. Download your converted JPG file.

Quality and File Size

The JPG quality setting lets you control the trade-off between file size and visual fidelity. A quality of 90% typically provides excellent results with significant file size reduction. Lower values produce smaller files with more visible compression artifacts.

Privacy and Browser-Based Processing

The Affivance WebP to JPG converter processes everything locally in your browser. Your WebP files are never uploaded to any server. The conversion uses the browser's native Canvas API, making it fast, private, and secure.

JPG to PNG Converter – Convert JPEG Images to PNG Format

Converting JPG to PNG is useful when you need lossless image quality, transparency support, or compatibility with design workflows that require PNG files. The Affivance JPG to PNG converter makes this process instant and completely private.

JPG vs PNG: Key Differences

JPG uses lossy compression, which reduces file size but discards some image data each time it is saved. PNG uses lossless compression, preserving every pixel exactly as it is. PNG also supports transparency (alpha channel), which JPG does not. While PNG files are typically larger than JPG files, they are ideal for graphics, screenshots, logos, and images where quality must be preserved perfectly.

Why Convert JPG to PNG?

• Preserve image quality without further lossy compression
• Prepare images for editing workflows that require PNG
• Ensure pixel-perfect reproduction for graphics and text
• Create a base image that can later have transparency added

How the Conversion Works

The Affivance JPG to PNG converter loads your JPG image into the browser's Canvas, then exports it as a PNG file. Since PNG is lossless, the output preserves the exact pixel data from your JPG. Note that converting JPG to PNG does not restore quality lost during the original JPG compression — it simply prevents further quality loss.

Browser-Based Privacy

Your JPG files are processed entirely within your browser. No files are uploaded to any server, and no external services are used. The conversion is instant and completely private.

PNG to JPG Converter – Convert PNG Images to JPEG with Custom Background

Converting PNG to JPG is one of the most common image format conversions. JPG files are smaller and universally supported, making them ideal for photographs, web images, and email attachments. The Affivance PNG to JPG converter gives you full control over quality and background color.

PNG vs JPG: Why Convert?

PNG files are often significantly larger than JPG files because PNG uses lossless compression. For photographs and complex images where slight quality loss is acceptable, JPG provides much smaller file sizes. This makes JPG the preferred format for web pages, social media, and email.

Handling PNG Transparency

JPG does not support transparency. When you convert a transparent PNG to JPG, the transparent areas must be filled with a solid background color. The Affivance converter lets you choose any background color, with white as the default. This ensures your converted JPG looks exactly as intended.

How to Convert PNG to JPG

1. Upload your PNG file using the upload button or drag and drop.
2. Adjust the JPG quality slider for your desired balance of size and quality.
3. Choose a background color if your PNG has transparency.
4. Click "Convert to JPG" and download the result.

Browser-Based Processing

All conversion happens locally in your browser using the Canvas API. Your PNG files are never uploaded to any server. The process is fast, private, and works without any software installation.

Image to PDF Converter – Convert JPG and PNG to PDF Online

Converting images to PDF is essential for creating professional documents, portfolios, reports, and printable files. The Affivance Image to PDF converter lets you combine multiple JPG, PNG, and WebP images into a single PDF document — entirely in your browser.

What Is Image to PDF Conversion?

Image to PDF conversion takes one or more image files and embeds them into a PDF document. Each image becomes a page in the PDF. This is useful for creating photo albums, document scans, presentation materials, and printable portfolios.

JPG to PDF and PNG to PDF

This tool supports JPG, PNG, and WebP images as input. You can mix different formats in the same PDF. Whether you need to convert a single JPG to PDF or combine dozens of PNG images into one document, the process is the same: upload, arrange, and generate.

Page Size, Orientation, and Layout Options

The Affivance converter offers flexible PDF settings:

• A4 — Standard international paper size (210 × 297 mm)
• Letter — Standard US paper size (8.5 × 11 inches)
• Original — Each page matches the image's pixel dimensions
• Portrait/Landscape orientation control
• Adjustable margins for professional layout
• Fit, Fill, or Original size image placement

Multiple Images to One PDF

You can upload multiple images at once or add more images incrementally. Reorder them using the up and down buttons, remove individual images, or clear all and start over. The final PDF will contain your images in the exact order you arrange them.

Privacy and Browser-Based PDF Creation

The PDF is generated entirely in your browser using custom Vanilla JavaScript. No files are uploaded to any server, and no external PDF library is used. Your images remain completely private throughout the process.
