How to Resize and Convert Images Online

Universo Soft is a browser-based tool that lets you resize images without uploading them to a server. Here is how to process your photos quickly:

1

Upload Images

Drag and drop your JPEG, PNG, or WebP images into the dotted box above. We support bulk uploading, so you can select hundreds of files at once.

2

Configure Resize Settings

Choose Scale % to reduce file size by a percentage (e.g., 50% for thumbnails). Use Dimensions to fit images into specific width/height constraints (e.g., 1920x1080).

3

Process & Download

Select your output format (convert PNG to JPG, or modernize with WebP/AVIF). Click "Process Images" and download your optimized files instantly as a ZIP archive.

About Us

Building tools that respect your privacy and save your time.

Universo Soft was founded by a team of web developers who were tired of slow, ad-riddled, and privacy-invasive online converters. We set out to build a tool that we would want to use ourselves: one that is clean, efficient, and runs entirely on the client-side.

Our Mission

To make high-quality image optimization accessible to everyone, directly in their browser, without ever compromising user data privacy.

Frequently Asked Questions About Image Processing

Find answers to common questions about image resizing, compression, and optimization.

More Common Questions

Upload any image, select "ICO (Favicon)" as output format, and set dimensions to 16x16, 32x32, or 64x64 pixels. ICO format supports multiple sizes in one file. Our tool automatically creates proper ICO files for website favicons with correct color depth and transparency handling.

Yes! We preserve animation when resizing GIFs. The tool processes each frame while maintaining the animation sequence. For better compression, consider converting to animated WebP, which typically reduces file size by 50-90% while maintaining quality. Note: Complex GIFs with many frames may take longer to process.

Browser canvas limitations apply (typically 16,384x16,384 pixels). For most practical purposes, 8K (7680x4320) is the maximum recommended. For larger prints or special applications, process in specialized desktop software. Our tool warns you if you exceed reasonable limits for web use.

Resize to max 1000px width, use JPEG format at 70-80% quality, and keep files under 200KB each. Email clients have strict size limits. Use our "Email Optimize" preset which automatically applies these settings. Always test send to yourself before mass email campaigns.

Yes, but note: SVG resizing works differently. Since SVG is vector-based, resizing doesn't lose quality. Our tool rasterizes SVG to pixel-based formats (PNG, JPEG, etc.) at your specified resolution. For pure SVG editing, use vector software. For web use, converting SVG to PNG/WebP ensures compatibility.

Chrome, Firefox, Safari, Edge (latest versions). Mobile browsers on iOS and Android. IE11 is not supported. For AVIF support: Chrome 85+, Firefox 93+, Edge 93+. For WebP: Chrome 17+, Firefox 65+, Safari 14+, Edge 18+. Older browsers may have format limitations.

Our tool automatically adds "_resized" suffix. For custom naming, download as ZIP and rename locally, or use dedicated renaming software. We maintain original names to prevent confusion when processing multiple files. Future updates may include advanced renaming options.

DPI/PPI (dots/pixels per inch) only matters for printing, not screen display. Web browsers ignore DPI. For printing: 300 DPI is standard. Our tool preserves original DPI metadata. Changing pixel dimensions affects print size (more pixels = larger print at same DPI).

Not currently. Our focus is on core resizing/compression. For watermarks, use photo editing software first, then optimize with our tool. Watermarking requires additional complexity that could impact processing speed and simplicity. Consider this for professional photography portfolios.

Our advantages: No installation, 100% private (no uploads), free, works on any device, simple interface, modern format support (WebP/AVIF), bulk processing, and no watermarks. Desktop software offers more features but requires installation, updates, and often costs money. We're ideal for quick, secure optimization.
