What You Can Resize
Why Use a Browser-Based Resizer?
Traditional online resizers upload your file to a server, process it, and send it back. That is slow, eats bandwidth, and exposes your photos to strangers. PhotoFlip's resizer does everything in your browser using the HTML canvas API. No file ever leaves your device, which means it is faster, private by default, and works offline after the page loads.
You get the same high-quality bicubic resampling the major desktop editors use — enabled via imageSmoothingQuality: 'high' — and you can save as JPG, PNG, or WebP with fine-grained quality control. For truly huge outputs, WebP typically produces 25–35% smaller files than JPG at the same visual quality.
Resize vs Upscale vs Crop
These three operations get confused often. Here is what each one actually does.
Resize
Changes pixel dimensions. Makes the photo larger or smaller without adding or removing image content.
Upscale
Uses AI to reconstruct detail when going from low to high resolution. Try the Image Upscaler.
Crop
Trims away a rectangular region and keeps only a portion of the original. Use the Image Cropper.

JPG, PNG, and WebP. You can also control quality for JPG and WebP from 1% to 100%.
Up to 16,384 × 16,384 pixels per side, limited only by browser memory. Most devices handle 4K and 8K output without issue.
By default, yes. Toggle the lock icon between width and height to type custom non-proportional dimensions.
Yes. Built-in presets cover Instagram, Facebook, Twitter/X, LinkedIn, Pinterest, YouTube, and TikTok — plus print sizes (A4, Letter, 4×6, 5×7) and document sizes (passport photos, favicons, app icons).
Downscaling (making smaller) produces sharp results. Upscaling (making larger) may soften detail because the original pixels are simply stretched. For true AI upscaling that reconstructs detail, use the Image Upscaler tool.
This tool processes one image at a time. For bulk resizing, resize each photo in sequence — each operation only takes a few seconds.
Resizing changes the pixel dimensions of the entire image (it stretches or shrinks). Cropping selects a rectangular portion of the image and discards the rest. Use the Image Cropper for cropping.
