What is a JPG file?
JPG (or JPEG) is the most widely used photo format. Cameras, phones and almost every app create it, and it opens on any device, browser, printer and website. JPEG uses lossy compression: it drops detail the eye barely notices to keep files small, and the quality setting controls that trade-off. It has no transparency and loses a little quality each time it is re-saved. People convert to JPG for maximum compatibility, and convert from JPG when they need transparency, lossless edits or a PDF.
How to open a JPG file
- Windows: Photos opens JPG files by default.
- Mac: double-click to open in Preview.
- iPhone: tap the file in Files or save it to Photos.
- Android: opens in Google Photos or any gallery app.
How Canvas Cropping Works and Its Trade-Offs
Our cropping engine relies on the browser's native canvas API to isolate a specified sub-rectangle from your visual matrix without altering the core file container. Each image retains its original format upon export, ensuring PNG transparency is preserved while JPG and WebP photos keep their standard compression behavior. When you apply a batch crop, the exact same coordinate offsets are applied uniformly across every image. The primary trade-off of cropping is resolution reduction: discarding outer pixels shrinks the total pixel dimensions, making centered percentage presets ideal for keeping focal subjects sharp.
When You Need to Crop Images
Use 1:1 for square posts, 4:5 for portrait feed posts, and 9:16 for full-screen Stories and Reels across social networks. Batch cropping also helps you quickly trim white borders from scanned documents or standardize aspect ratios across up to 10 e-commerce product photos at once. Additionally, it streamlines everyday photo prep by letting you quickly extract headshots from wide group photographs or reframe horizontal landscape pictures for vertical mobile wallpapers without installing heavy desktop photo editors.
Why convert in your browser?
Most online converters send your files to their servers and promise to delete them later. FileFlip does the work on your own device instead, so there is nothing to delete: you can even switch on airplane mode after the page loads and it keeps working. See the privacy proof
Frequently asked questions
Does cropping an image change its file format?
No, the output keeps your original input format. If you upload a JPG, PNG, or WebP, the cropped result downloads in that identical format.
Will cropping reduce the quality or resolution of my photo?
Cropping removes peripheral pixels, which decreases the total pixel resolution of the image. However, the remaining cropped area is rendered at full fidelity without artificial downscaling or extra lossy compression.
How does batch cropping work across multiple images?
When you adjust the crop percentages or select a preset ratio, that exact same crop geometry is applied to all images in your batch (up to 10 files). You can then download each file individually or bundle them all into a ZIP archive.
What aspect ratio should I use for social media posts and stories?
Use 1:1 for square posts, 4:5 for portrait feed posts, and 9:16 for Stories and Reels. For horizontal banners or widescreen displays, select 16:9.
Can I crop images while offline?
Yes. Because all image processing runs entirely in your browser using canvas technology without uploading files, the tool functions in airplane mode after your first visit.
What is the maximum file size I can crop?
There is no fixed file size limit because processing is handled locally by your browser rather than an external server. You can crop up to 10 JPG, PNG, or WebP images per batch with unlimited conversions.
