Core Features

One-stop online solution for image compression, format conversion, and resizing. Supports batch processing for all major formats including JPG, PNG, WebP, AVIF, and HEIC.

Compress JPG

To significantly boost your website's loading speed and save storage, it's crucial to compress JPG files. Our tool uses advanced algorithms to reduce file size while maintaining excellent quality, making it ideal for web design, emails, and social media.

Compress PNG

For web designers and app developers, it's vital to compress PNG files to improve load times. Our tool offers lossy and lossless options to drastically reduce file size while fully preserving the transparency that makes PNGs so versatile.

Compress Image

Optimizing your website's performance and saving storage is easy when you compress images. Our universal tool supports JPG, PNG, and WebP, intelligently reducing file sizes with advanced algorithms while preserving maximum visual quality.

WebP to JPG

Facing compatibility issues with WebP images? Our WebP to JPG converter is the solution. It seamlessly transforms modern WebP files into the universally accepted JPG format, ensuring your images are viewable and shareable on any device or platform.

WebP to PNG

When you need to use a transparent WebP in software that doesn't support it, our WebP to PNG converter is your best choice. This feature losslessly transforms your WebP file, ensuring the alpha channel information is fully and correctly preserved.

PNG to JPG

When transparency is no longer needed, our PNG to JPG converter is perfect for saving storage and speeding up network transfers. This common image handling task allows you to convert your PNG images into smaller, more compatible JPG files.

HEIC to JPG

To break free from Apple's ecosystem, our HEIC to JPG converter is an essential tool. It easily changes HEIC photos from your iPhone into the universal JPG format, solving compatibility issues on Windows, Android, and web platforms for seamless sharing.

HEIC to PNG

For professional design work that demands quality, our HEIC to PNG converter is the ideal choice. It losslessly transforms HEIC files into high-quality PNGs, ensuring that all image details and any potential transparency are perfectly maintained.

AVIF to JPG

To ensure your modern, highly-compressed images display correctly everywhere, use our AVIF to JPG converter. This feature addresses the limited compatibility of the advanced AVIF format by changing it to the ubiquitous JPG format.

AVIF to PNG

Our AVIF to PNG converter provides the best compatibility for next-gen AVIF images that require transparency. It's an essential tool for ensuring consistent, high-quality results in professional design and web publishing by creating a lossless PNG.

JPG to WebP

A key step in modern website optimization is to convert JPG to WebP. Our tool helps you adopt Google's recommended format, reducing image size by up to 70% with almost no quality loss, which dramatically improves page speed, UX, and SEO ranking.

PNG to WebP

For PNGs with transparency, converting PNG to WebP is the best practice for performance. The WebP format is smaller, more efficient, and supports transparency, making it the preferred choice in modern web design to balance quality and speed.

JPG to PNG

To avoid quality degradation during editing, use our JPG to PNG converter. This is crucial when you need to perform further edits or require the highest image quality for printing or display, as it converts the lossy JPG to a lossless PNG format.

JPG to AVIF

Experience cutting-edge compression by converting JPG to AVIF. This process achieves an even higher compression ratio than WebP for ultimate file size optimization, a vital step for developers pursuing peak performance and future-proof standards.

PNG to AVIF

As a future-proof upgrade for your images, convert PNG to AVIF. This format supports transparency and HDR with superior compression, making it the best choice for applications that demand top-tier performance and visual quality.

Options Guide

Understand the function and usage of each option to optimize your image conversion results.

1

Compression Quality

This option only applies when the target format is JPG, WebP (Lossy), or AVIF (Lossy).

A lower value creates a smaller file but reduces image quality. The recommended value of 75 offers a good balance between file size and quality.

If the file is still too large after compression, try reducing the resolution, which is often more effective for shrinking file size.

2

Resolution Adjustment

Reduce the image resolution by a percentage while maintaining the original aspect ratio. 100% preserves the original dimensions.

Reducing the resolution can significantly reduce the file size. If you don't need the original's high resolution, this is often the most effective way to make the file smaller.

With other options being the same, based on 100% resolution. Adjusting to 75% resolution reduces the file size by an average of 30%; adjusting to 50% resolution reduces it by an average of 65%; adjusting to 25% resolution reduces it by an average of 88%.

3

Output Format

Choose the output format for the image. Different formats have their own advantages and use cases.

Auto Compress: This option automatically applies a suitable compression strategy based on the input format:

  • JPG inputs are compressed as JPG.
  • PNG inputs are compressed using the PNG (Lossy) method.
  • WebP inputs are compressed using the WebP (Lossy) method.
  • AVIF inputs are compressed using the AVIF (Lossy) method.
  • HEIC inputs are converted to JPG.

You can also manually select a format below based on your specific needs. Here’s a detailed guide to each option:

JPG: The most popular image format, though it doesn't support transparency. When converting from an uncompressed PNG, it can reduce file size by an average of 90%. At a quality setting of 75, the quality loss is often imperceptible. If you don't need a transparent background (which is true for most photos), converting to JPG is usually the best choice.

PNG (Lossy): Supports transparency with some quality loss, reducing file size by an average of 70% compared to an uncompressed PNG. Choose this only if you need a transparent background in the PNG format. Otherwise, JPG offers better quality for a smaller size (without transparency), and WebP (Lossy) provides better quality, smaller size, and transparency, making it a superior alternative if the PNG format isn't a strict requirement.

PNG (Lossless): Supports transparency with no quality loss. Reduces file size by an average of 20% compared to an uncompressed PNG. However, if the PNG format is not a strict requirement, WebP (Lossless) is a better choice as it offers smaller file sizes.

WebP (Lossy): Supports transparency with slight quality loss. Reduces file size by an average of 90% compared to an uncompressed PNG. It's an excellent replacement for PNG (Lossy), offering better quality and smaller sizes. Note: WebP is not supported on some older devices.

WebP (Lossless): Supports transparency with no quality loss. Reduces file size by an average of 50% compared to an uncompressed PNG, making it a superior replacement for PNG (Lossless). Note: WebP is not supported on some older devices.

AVIF (Lossy): Supports transparency with slight quality loss. As the successor to WebP, it offers an even higher compression rate, reducing file size by an average of 94% compared to uncompressed PNG. As a cutting-edge format, AVIF provides excellent quality at very small file sizes. However, browser and device compatibility is still limited. This format is best for advanced users or when you are certain the target devices support it.

AVIF (Lossless): Supports transparency with no quality loss. Compared to an uncompressed PNG, the file size reduction is not significant, and in some cases, may even increase. Unless you have a specific need for lossless AVIF, PNG (Lossless) or WebP (Lossless) are generally better options.
