Frequently Asked Questions 🤔

An online image resizer is a web-based tool that allows you to change the dimensions (width and height) of your images directly in your browser. Our tool at imageresizeronline.net makes this process quick and easy without needing to install any software.

Resizing images is crucial for web performance, social media posts, and email attachments. Smaller images load faster on websites, fit the required dimensions for platforms like Instagram and Twitter, and are easier to send via email.

Image compression is the process of reducing an image's file size. There are two main types: lossy and lossless. Lossy compression (like JPEG) removes some data to make the file much smaller, while lossless compression (like PNG) reduces size without losing any quality.

Yes, our image resizer and compressor is completely free to use. There are no hidden charges or subscription fees for using the core features of our tool.

We support all major image formats, including JPEG (or JPG), PNG, WEBP, and GIF. You can upload any of these formats and also convert between them during the resizing process.

It's simple! First, upload your image. Second, enter your desired new width or height. Third, choose your compression and format options. Finally, click 'Process Image' to download your newly resized picture.

Currently, our tool processes images one by one to ensure the best quality and control over each file. We are exploring options for batch processing in the future.

Maintaining the aspect ratio ensures that your image is not stretched or distorted. When you enter a new width, our tool automatically calculates the correct height to keep the image's proportions, and vice versa.

To compress an image without resizing it, simply upload your file, leave the width and height fields blank, and adjust the 'Compression Quality' slider to your desired level before processing.

Absolutely. You can easily convert image formats by uploading your file (e.g., a PNG) and then selecting your desired output format (e.g., JPEG) from the options before you process the image.

Enlarging an image can reduce its quality as the software has to guess what the new pixels should be. Reducing an image's size generally maintains quality well, but high levels of compression can introduce visible artifacts.

JPEG is best for photographs due to its excellent lossy compression. PNG is ideal for graphics with sharp lines or transparency because it uses lossless compression. WEBP is a modern format from Google that offers superior compression for both lossy and lossless images, often resulting in smaller file sizes than both JPEG and PNG. You can learn more about image file formats online.

For most web uses, a quality setting between 75-85 provides a great balance of small file size and high visual quality. For high-resolution prints, you might want to use 90 or above.

DPI stands for 'Dots Per Inch' and is primarily relevant for printing. Our online tool focuses on pixel dimensions (width and height) for digital screens. While we don't directly change the DPI metadata, resizing the pixel dimensions is the most important step for web use.

Unfortunately, significantly enlarging a small image will always result in some quality loss. This process, called interpolation, requires the software to create new pixels, which can lead to blurriness or pixelation.

Yes. We take your privacy very seriously. All images uploaded to our servers are automatically and permanently deleted after 30 minutes. We do not view, share, or store your files.

No. Both the original image you upload and the processed version are permanently deleted from our servers 30 minutes after you upload them.

Yes, our process is automated and secure. Since all files are deleted automatically after a short period, your personal photos are not stored on our systems.

Never. Your images are used solely for the purpose of providing the resizing and compression service you have requested. They are not used for any other purpose whatsoever.

Yes, our website uses SSL (HTTPS) encryption, which means all data transferred between your browser and our server is secure and private.

Uploads can fail if the file is larger than our maximum limit of 5MB or if it is not a supported file type (JPEG, PNG, WEBP, GIF). Please check your file and try again.

Blurriness can occur if you are significantly enlarging a small image. Try starting with a higher-resolution original file. If you are reducing the size, ensure the compression quality is set to a higher value (e.g., 85 or above).

This can happen in rare cases, for example, if you convert a highly compressed JPEG to a PNG (a lossless format) or if the original image was poorly optimized. Try adjusting the output format and quality settings.

Our current tool processes animated GIFs by resizing only the first frame, which removes the animation. We are working on adding support for resizing animated GIFs while preserving their animations.

Yes, our website is fully responsive and designed to work seamlessly on all devices, including mobile phones, tablets, and desktop computers.

Image optimization for SEO involves reducing the file size of your images to help your website load faster, which is a key ranking factor for Google. Using descriptive file names and alt text are also important. Our tool is perfect for the file size reduction part of SEO.

Our tool allows you to control the quality, which directly impacts file size, but it does not have a feature to target an exact file size. You can try processing the image with different quality settings to get close to your target.

For logos, PNG is often the best choice because it supports transparency and uses lossless compression, which keeps text and sharp lines crisp and clear.

After uploading a resized image to your website with the same file name, you may need to do a 'hard refresh' in your browser (Ctrl+F5 on Windows, Cmd+Shift+R on Mac) to see the changes and bypass the browser's cache.

A common recommendation for full-width blog post images is around 1200 pixels wide. This provides good quality on most screens without creating an unnecessarily large file. Always check your specific website's theme for optimal sizes.
