Image Resizer

No. Your images are processed locally in your browser, so resizing doesn’t require uploading your files. Quick tip: If a file is huge and feels slow, resize dimensions first to reduce memory usage. Common mistake: Uploading a small screenshot and then scaling up—upscaling will look soft.

Start from a larger source, resize down (not up), and export at higher quality (JPG ~90–95). Quick tip: Use PNG for text/logos to keep edges sharp. Common mistake: Upscaling small images—quality loss is unavoidable.

Yes, but first convert to pixels using DPI (pixels = inches × DPI). Quick tip: For screen work, use pixel sizes directly for best results. Common mistake: Entering inches/cm without DPI—results won’t match expectations.

Use Instagram presets: Story/Reels 1080×1920 (9:16), Post 1080×1080 (1:1) or 1080×1350 (4:5), Landscape 1080×566 (1.91:1). Quick tip: If unsure, start with 1080×1920 for vertical content and keep key text centered. Common mistake: Resizing a square post to Story size without repositioning—edges get cut.

It’s a browser-based Instagram resizer—no download and no upload required. Quick tip: For very large images, desktop browsers tend to be faster than mobile. Common mistake: Trying to resize giant files on older phones—browser memory can fail.

Yes. Use the Batch Resizer to apply one size to many images. Quick tip: If you need per-image crop focus, resize them one by one. Common mistake: Uploading dozens of huge files on mobile—memory limits can slow things down.

Use Crop to fill the target size (edges may be cut). Use Pad to keep the entire image visible (adds background/space). Quick tip: If your design has text near edges, Pad is usually safer. Common mistake: Using Crop for posters with edge text—important text often gets cut.

Blurry results usually come from a low-resolution source or heavy compression during export. Quick tip: For photos export JPG at ~90–95; for text/logos use PNG. Common mistake: Exporting JPG at very low quality to “save size”—it ruins sharp edges and text.

Choose Pad to preserve everything, or use Crop and adjust the focus/position to keep the subject centered. Quick tip: Keep key content in the center area whenever possible. Common mistake: Placing faces or text right at the edges—most crops remove edges first.

JPG is best for photos, PNG is best for text/logos or transparency, and WebP is often the smallest if supported. Quick tip: If you’re unsure about compatibility, use JPG/PNG. Common mistake: Using PNG for large photos—file size often becomes unnecessarily big.

Yes. Export as PNG (or WebP with alpha if available). JPG does not support transparency. Quick tip: If you need a solid background, use Pad and pick a matching color. Common mistake: Exporting a transparent design as JPG—background will turn solid.

Yes on modern mobile browsers, but performance depends on your device and image size. Quick tip: If it’s slow on mobile, try fewer images or a smaller source file. Common mistake: Editing ultra-large images on older phones—browser memory can fail.

Crop fills the target size (may cut edges). Pad fits the whole image and adds background/space.

JPG for photos, PNG for text or transparency, WebP for smaller files (if supported).

Use a higher-resolution source and export with higher quality.

Very large files can exceed browser memory limits on some devices.
