Start with the job you came for.
The most common things people need to do with a video or photo, one click away.
The upload is the slowest part. So we removed it.
Most converters take your file, put it on a server, queue it behind other jobs, and send back a link. Cutmoor opens the file in your browser, encodes it with WebAssembly or the canvas API, and saves the result straight to your downloads folder.
That means no upload wait, no storage bucket, and no third party holding a copy of your footage or photos. It also means the limits are honest: your device's memory is the ceiling, not a subscription tier.
How Cutmoor worksThere is no upload endpoint. The encoder runs in the page, and the file is released when you close it.
Open the page and start. The first video job loads the encoder once; the browser caches it for the next one.
Presets for Reels, Shorts, TikTok, WhatsApp, Instagram posts, YouTube thumbnails, and link previews.
Drop. Choose. Done.
Three steps, whether the job is a 12-second Reel, a 48-megapixel photo, or a 40-minute screen recording.
- 01Drop your file
The browser reads the duration, format, and dimensions locally. Nothing is sent anywhere.
- 02Pick the outcome
Target size, aspect ratio, format, or timestamp. The presets match the platforms people actually use.
- 03Take the export
Download a clean file. No watermark, no account, no “upgrade to remove the limit” screen.
Know the limit before you hit it.
WhatsApp's chat limit is roughly 16 MB, and it re-encodes whatever you send. Pick the right target bitrate, export once, and your video survives the trip.
Social mediaSocial media image sizes for 2026 (and why the feed still crops them)A 1080 × 1350 photo is the safe portrait post for Instagram. A 1200 × 630 image is the safe link preview. Everything else is a crop decision.
ConversionHEIC to JPG: why iPhone photos need converting (and how to do it safely)HEIC is an efficient Apple format built on HEVC. It is smaller than JPG, but many apps still refuse it. Converting to JPG is a compatibility fix, not an upgrade.
ConversionPNG vs JPG vs WebP: which image format should you use?PNG is lossless, JPG is universal, and WebP is usually smaller. The right choice depends on what is in the image and where it is going.
What people ask before the first file.
Does Cutmoor upload my video or image?
No. Video is encoded inside your browser with WebAssembly, and images are decoded and re-encoded with the canvas API. Files are read from your device, processed in memory, and saved back to your device. There is no Cutmoor server that receives them.
Is Cutmoor really free?
Yes. Every video and image tool is free, with no account, watermark, or export limit. The site is supported by advertising, which keeps every tool free.
Which formats can I use?
Video inputs include MP4, MOV, WebM, MKV, and AVI. Image inputs include JPG, PNG, WebP, AVIF, GIF, BMP, HEIC, and HEIF. Exports include MP4, WebM, GIF, MP3, WAV, M4A, JPG, PNG, and WebP, depending on the tool and your browser.
Can Cutmoor download a video from YouTube or Instagram?
No. Cutmoor only works with files you already have. It does not fetch URLs or download content from streaming platforms, and it cannot bypass a platform player.
How big can a file be?
Browser memory is the real limit. Video files up to about 500 MB work on a desktop with 8 GB of RAM, while phones and older laptops should stay under 200 MB. Image output is capped at 16.7 megapixels for canvas safety, and very large photos are scaled down before export.
Do I need to install anything?
No. Cutmoor runs in a modern browser on desktop, tablet, and phone. The first video job downloads the encoder once and the browser caches it. iPhone HEIC files may download a separate 3 MB local decoder on Chrome, Edge, and Firefox; Safari uses the system decoder.
Why can't I export WebP in Safari?
Safari can display WebP but cannot encode it from a canvas, and it silently returns a PNG instead. Cutmoor tests the encoder at runtime and disables WebP export when it is unavailable, so a file with a .webp extension is never actually a PNG. JPG and PNG remain available.
Make the file fit. Keep the quality.
Video and image tools, local processing, and an export that does not ask you to make an account.
