Free Image Compressor for JPG, PNG, WebP & HEIC
Compress JPG, PNG, WebP, HEIC, and TIFF images while keeping image quality as high as possible.
All compression is processed on the server, providing consistent and reliable results regardless of your device performance.
Upload your files, choose the compression quality, and click the compress button to get started.
Image resizing is also supported, making it useful for preparing files for websites, online stores, social media, and platforms with upload size limits.
Choose the right compression level for your needs, including product photos, blog images, email attachments, and more.
If you want to convert images to WebP, try the WebP Converter. If you need additional editing features, you can also use the Image Editor.
Why JPG, PNG, and WebP Compression Results Are Different
Each image format uses a different compression method, so file size and image quality can vary even when the same compression settings are applied.
JPG is best for photographs and colorful images, usually producing the smallest file sizes after compression.
PNG is ideal for transparent graphics, screenshots, and text-based images while supporting lossless compression.
WebP generally provides better compression efficiency than JPG while maintaining similar visual quality.
How to Reduce Image Resolution and File Size at the Same Time
There are two common ways to reduce image file size: increasing compression or lowering the image resolution.
The Vivoldi Image Compressor lets you handle both at the same time.
Simply enter a target width or height in the resize settings.
If you enable automatic aspect ratio, the image will be resized while preserving its original proportions.
This is especially useful for optimizing images for websites, blog posts, online stores, thumbnails, and other platforms with file size limits.
Image Compression Quality Guide
Vivoldi offers Auto, High Quality, Medium Quality, and Low Quality presets, along with manual compression levels ranging from 95% down to 70%.
If you want minimal visible quality loss, High Quality or settings above 85% are recommended.
If reducing file size as much as possible is your priority, the 70–75% range usually provides the best balance.
The Auto option analyzes image complexity and transparency to optimize both image quality and file size automatically.
If the result is not what you expected, you can reset the settings and try a different compression level at any time.
Compress Large TIFF and RAW Image Files
Studio photos and original editing files can easily exceed 10MB to 20MB per image.
Uploading or sharing these files without compression can slow down transfers and quickly consume storage space.
Vivoldi processes large image files including TIFF directly on the server, allowing compression to run smoothly regardless of your device performance.
Free users can process files up to 20MB per image.
How Are Files Saved After Compression?
Once compression is complete, click the Download button on the results page to save your file.
The compressed file keeps the original filename, and no account is required to download it.
Files uploaded to the server are automatically deleted after a certain period of time.
If multiple images were compressed, each file can be downloaded separately.

Frequently Asked Questions
Yes, the tool is free to use. Free users can process up to 20MB per file and 5 files per upload.
No software installation or account registration is required — everything works directly in your web browser.
If you need to process larger files or compress many images at once, you can upgrade to a paid plan for higher limits.
Yes. Vivoldi performs image compression directly on the server, helping reduce quality loss compared to many browser-based or local compression tools.
If you select the High Quality option, you can significantly reduce JPG file size while keeping the image visually sharp and detailed.
Yes. You can upload WebP files directly and compress them while keeping the original format unchanged.
If you want to convert JPG or PNG images to WebP while also reducing file size, use the WebP Converter first.
Yes. You can upload HEIC photos taken on an iPhone directly and reduce their file size without converting them to another format first.
No. The original file format is preserved during compression.
If you upload a JPG, the compressed result will remain JPG. The same applies to PNG, WebP, HEIC, and other supported formats.
No. Once an image has been compressed, it cannot be perfectly restored to its original state.
Image compression works by reducing or removing data, and discarded image data cannot be recovered later.
If you may need the original image in the future, it is recommended to keep a separate backup of the original file before compression.
Vivoldi uses uploaded images only for compression processing, and files are automatically deleted from the server after a certain period once processing is complete.
If an image contains sensitive personal information or confidential content, it is always recommended to review the service’s Privacy Policy before uploading files to an external server.
Some image compression tools do not fully account for the characteristics of different file formats, which can sometimes lead to unexpected results with PNG transparency or animated GIF files.
Vivoldi applies different optimization methods depending on the image format, including JPG, PNG, GIF, and WebP.
Each image type is processed separately to reduce file size while minimizing visible quality loss.
Vivoldi also applies additional optimizations tailored to the characteristics of each image, so results may vary depending on the image itself even at similar file sizes.
Multiple files can be processed at the same time, allowing you to compress large batches of images quickly without long waiting times.
