Image Compressor
Shrink JPEG, PNG, WebP and AVIF photos with a quality slider, live size preview and instant before-and-after comparison.
Compress and upscale images, merge and split PDFs, trim, merge and watermark video, convert audio formats, record your screen or webcam. Files never leave your device.
Compress, convert, crop, watermark and upscale photos, or pull the text out of a screenshot or scan. Every file is processed in your browser, so nothing is uploaded.
Shrink JPEG, PNG, WebP and AVIF photos with a quality slider, live size preview and instant before-and-after comparison.
Convert between JPG, PNG, WebP, AVIF and GIF formats in bulk.
Cut a photo down to the part that matters. Drag the frame, lock an aspect ratio like 1:1 or 16:9, straighten it with a 90 degree rotate, then export at full resolution.
Change the pixel size of a photo by typing a width and height, or pick a quick percentage. Keep the aspect ratio locked so nothing stretches, and export as JPG, PNG or WebP.
Stamp a name, brand or copyright line onto your photos. Control the position, size, colour, opacity and rotation, preview the result live, and export a whole batch at the original resolution.
Enlarge a photo 2x, 3x or 4x with an AI model that rebuilds edge contrast and clears up compression noise as it scales. Keep transparent backgrounds intact, compare both sides at the same size, all without uploading a single file.
See exactly what a photo reveals about you and the place it was taken, then strip the metadata out losslessly, so the pixels stay byte for byte identical.
Read the text out of a photo, a screenshot or a scanned page and get it back as copyable plain text.
Merge, split, protect, unlock and compress documents, or pull the text back out of a scan. Nothing goes to a conversion server, every page is processed on your own machine.
Combine several PDFs into one document. Drag the files into the order you want, merge them, and download the result. Pages are copied rather than re-encoded, so text stays selectable and images keep their resolution.
Cut one document into parts by page range, one file per page, or a fixed number of pages.
Turn JPG, PNG and WebP photos into a single PDF with A4 or Letter pages.
Render every page as a JPG or PNG at screen, good or print resolution.
Reorder, rotate and delete pages on a thumbnail grid, then stamp on page numbers and export.
Turn sideways or upside down pages the right way up. Rotate 90 or 180 degrees across the whole document, or only the pages you name, without touching anything else.
Add AES-256 password protection and decide whether printing, copying and editing are allowed.
Remove a password or the permission flags from a PDF you can already open.
Reorganise a PDF into a tighter structure without re-encoding a single page or image.
Pull the words out of a PDF as copyable text. Digital pages are read instantly, scanned pages go through OCR.
Stamp page numbers onto every page. Choose the corner, the wording (1, Page 1 or 1 / N) and the first number, and skip the cover page if you want. Nothing is re-encoded, so the text stays selectable.
Lay a word such as CONFIDENTIAL across every page, tiled diagonally or placed once in the middle, with your own size, colour, opacity and angle.
Draw your signature with a mouse or a finger, or upload a picture of it, then drop it on the page you pick. The mark is stamped into the page as an image, not as a certificate.
Read the title, author, subject and keyword fields hidden inside a PDF, change them, or wipe the lot before the file goes out to a client.
Cut, join, rotate, speed up and watermark video, compress or convert a clip, make a looping GIF, or record your screen and webcam. Powered by FFmpeg running locally.
Reduce video file size with quality, resolution and frame-rate controls.
Convert videos between MP4, WebM, MKV and MOV, extract audio to MP3, or turn any clip into an animated GIF. Powered by FFmpeg running in your browser.
Set a start and end point on the timeline and export just the part you need. Choose a precise re-encode or a lossless stream copy.
Join several clips into one file. Reorder them in the list and the segments are normalised before they are stitched together.
Overlay your own text or logo on every frame. Set the corner, size, colour and opacity, with no watermark added by us.
Turn a sideways clip the right way up, or mirror it. Rotate in 90 degree steps and flip horizontally or vertically.
Crop a clip to a square or a vertical ratio, choose which part of the frame to keep, and resize the output to 1080p, 720p or 480p.
Speed a clip up or slow it down from 0.25x to 4x. Keep the original pitch or mute the audio track.
Strip the soundtrack out of a clip and keep the picture as it was. The video stream is copied instead of re-encoded, so the export is quick and the quality is untouched.
Turn any clip into a looping GIF with an exact trimmed range, custom frame rate and a sharp 256 colour palette.
Record your screen, window or tab with optional mic audio.
Record yourself with your camera and microphone, right in the browser.
Pull still images out of a video. Grab one frame at a chosen timestamp, every few seconds, or ten evenly spaced shots, as PNG, JPG or WebP.
Bake an SRT, VTT or ASS subtitle file into the picture, so the captions show up on any player and any social platform. Font size, colour, outline and position are yours to set.
Move between SRT, VTT and ASS, or nudge the whole timeline a second earlier or later, without uploading the file or installing a player.
Pull the sound out of a video, change an audio format, or cut a clip to length. The audio never leaves your device.
Extract the audio track from an MP4, WebM, MOV or MKV clip and save it as MP3, M4A or WAV. Pick the bitrate you want, from 128 kbps for speech up to 320 kbps for music.
Convert between MP3, WAV, OGG, M4A and FLAC, with bitrate and sample rate controls.
Cut an audio file down to the part you need on an interactive waveform. Drag the selection to set the start and end, preview the clip before you commit, and add a fade in or fade out so the cut does not click. Export as MP3 or lossless WAV.
Slow a track down or speed it up without the chipmunk effect, or shift the pitch on its own by up to an octave. The two controls work independently.
Join several tracks into one file, and drag them into the order you want first. Different formats, sample rates and channel counts are all welcome, since every clip is resampled to a common setting before it is joined.
Shrink a recording to fit a size limit. Pick a bitrate yourself, or type the megabytes you are allowed and let the tool work out the bitrate that fits.
Turn a quiet recording up, or level several clips to the same loudness while you are at it. An optional limiter keeps the peaks from cracking when you push past six decibels.
Record your microphone straight from the browser, pause and resume as you go, then save the take or convert it to MP3. Nothing is sent to a server.
Six jobs that need a real AI model running on a server rather than in your browser. These upload your file to Volcengine AI MediaKit for processing, so they are different from everything above.
Cut the subject out of any photo in one click. Scenes for people, products and general objects, plus an optional outline and transparent PNG output.
Erase watermarks, captions, logos and stray objects, and let the AI rebuild the background behind them so nothing looks patched.
Rebuild the detail a small or compressed photo has lost. Three model tiers, a fidelity or texture strategy, and up to 4x enlargement.
Split a song into two tracks: the isolated vocals and the instrumental behind them, ready to download separately. Audio and video input.
Turn the speech in a video or audio file into a timed subtitle file. Download the transcript as SRT, VTT or plain text.
Upscale a soft or compressed clip to 720p up to 4K and clean up noise and blockiness with AI super resolution, with an optional frame rate change. Pro feature, up to 200 MB and 5 minutes per run.
Every tool follows the same simple flow, so you already know how to use them all.
Drop an image or video into the tool. Everything stays on your device and is never uploaded.
Pick quality, format or resolution with instant feedback. Watch the size change live.
Preview the output and download it instantly. No waiting, no watermarks, no limits.
Three things we never compromise on.
Image and video processing runs locally with WebAssembly. There is nothing to upload, so there is nothing to leak.
No queue, no processing server, no waiting. Adjust the quality slider and see the new file size update in real time.
All tools are free with no watermarks and no account. The work runs on your own device, so there is no daily cap and, for most tools, no file size limit at all.
Focused tools that do one job extremely well.
Compress JPG, PNG, WebP or AVIF with a granular quality slider and watch the byte count change live. Compare side by side before you download.
Best for: web pages, email attachments, social mediaFFmpeg compiled to WebAssembly runs directly in your browser. Compress huge videos or convert between formats without uploading a single byte.
Best for: sharing clips, storage savings, compatibilityCapture your screen, a single window, or your webcam with system audio. Pause and resume anytime, preview, then download as WebM or MP4.
Best for: tutorials, demos, presentations, vlogsAn ESRGAN network enlarges a photo 2x, 3x or 4x and rebuilds edge contrast along the way, so lines and text come out crisper than a plain resize would give. It runs on your own graphics chip, so nothing is uploaded and nothing is metered.
Best for: print, product shots, old photos, logosIt takes about five seconds. No sign-up, no upload, no charge.
