Questions about resizing, compressing, and converting images on Mac? This FAQ covers the basics, best formats, batch processing, and performance tips. If you need a fast way to batch process images on macOS, Freshly Squeezed is a solid option: freshlysqueezed.app.
Image resizing is changing an image’s dimensions (width and height), usually to fit a specific display area. Resizing is commonly used to optimize images for websites, email, apps, and social media.
Yes. Reducing an image’s dimensions usually lowers file size because fewer pixels are stored. For best results, resizing is often combined with compression.
Resizing changes the overall dimensions of an image. Cropping removes part of the image entirely and changes what’s visible. Cropping affects composition; resizing affects scale.
Image compression reduces file size by removing unnecessary data. Modern compression can often reduce file size significantly with little to no visible quality loss.
Lossy compression removes some image data to achieve smaller file sizes (common with JPEG). Lossless compression preserves all original data (often used with PNG and certain optimization modes).
It can. The goal is to balance file size and visual quality. Tools like Freshly Squeezed for macOS let you batch compress images while controlling quality so images stay sharp and load faster.
It depends on the content: JPEG is best for photos, PNG is great for graphics and transparency, WebP typically offers smaller files at similar quality, and AVIF can be even more efficient where supported.
Often, yes. WebP typically produces smaller file sizes than JPEG at similar visual quality, which can improve page speed and user experience.
AVIF can deliver excellent compression and quality, but support varies by browser and tooling. If you want maximum optimization and your audience supports it, AVIF is a strong choice.
Use a batch image processing app so you can apply the same settings to many images at once. Freshly Squeezed for macOS is built for batch resizing, compression, and format conversion.
Batch processing means applying the same edits—like resizing, compressing, and converting formats—to a set of images all at once. It saves time and keeps outputs consistent.
Desktop apps are usually faster, work offline, avoid upload limits, and keep images private since they’re processed locally. Freshly Squeezed processes everything on your Mac.
Yes. Properly sized and compressed images improve page speed and user experience, which can support better search performance and stronger Core Web Vitals.
Images should not be larger than the largest size they’ll be displayed. Resize to real display dimensions and compress aggressively while keeping the image looking good.
Resize to the required dimensions, then use modern compression settings that preserve detail. Freshly Squeezed for macOS is designed to batch optimize images while keeping them crisp.
Yes. Freshly Squeezed for macOS focuses on fast resizing, compression, and format conversion, especially for batch workflows.
Many people standardize their output settings and run repeatable batch workflows. A dedicated tool like Freshly Squeezed helps keep resizing and compression consistent across projects.
Yes. You can batch process images and export to common modern formats like JPEG, PNG, WebP, and AVIF (depending on your workflow and settings).
Resize to your theme’s recommended dimensions and compress images to keep product pages fast. Batch tools like Freshly Squeezed make it easy to optimize large catalogs consistently.
Resize images to the exact display size, compress them to reduce load time on mobile, and avoid massive files that slow down email rendering.
Each platform has preferred dimensions. Batch resizing lets you generate multiple versions quickly without manually editing every file.
