About this category
What image tools can do for you
Image tools are the most-used utilities on the web, and also the ones people are least comfortable uploading their files for. Every tool in this category runs entirely inside your browser using the Canvas and Image APIs: your photos are decoded, transformed and re-encoded on your own device, and the result is handed straight back to you as a download. Nothing is ever sent to a server.
Twenty tools sit in this category, and nearly all of them exist for the same reason: the format that was right for capturing an image is rarely the format that is right for publishing it. A phone shoots HEIC, a design tool exports PNG, a website wants WebP, and an email attachment limit wants something smaller than any of the three.
Choosing an output format
One rule settles most of these choices. If the image contains text, sharp edges or flat colour, keep it lossless. If it is a photograph, lossy is smaller and the difference is invisible at sensible quality settings.
What lossy compression actually discards
JPG and WebP work by transforming blocks of pixels and dropping the detail the eye is least likely to miss, which is mostly fine colour variation in regions that are already busy. Set the quality high enough and the loss is not visible. Set it low and you get ringing around edges and blotching in gradients.
The part that is rarely mentioned is that the loss is cumulative. Every time a JPG is decoded and saved again, another generation of detail goes, so opening a compressed image, cropping two pixels and exporting it costs quality even though the edit was trivial. Keep an untouched original of anything you expect to revise, and produce derivatives from that rather than from the last derivative.
Converting a PNG to a JPG also flattens transparency, because JPG has no alpha channel at all. Transparent pixels become whatever the converter paints behind them, which is almost always white. If a logo has a cut-out background, PNG to JPG shows the result before you download it, so check the edges rather than assuming.
WebP, and the one browser that will not write it
WebP is what the table above keeps pointing at: full alpha like PNG, animation like GIF, and lossy compression that beats JPG by roughly a quarter to a third on photographs. Browser support is now universal, which makes JPG to WebP the highest-value single conversion here for anyone publishing images to a website — it is usually the largest saving available without changing what the picture looks like.
There is an asymmetry worth knowing before you trust any converter, including this one. Every browser can display a WebP, but encoding one is a separate capability, and Safari only gained it in version 16.4 having decoded the format since version 14. A tool that does not check will happily hand you a PNG wearing a .webp filename on an older Safari, and the mistake surfaces later as a file far larger than it should be. These tools probe the encoder once and report the result rather than guessing.
The reverse direction matters too, and the two are not interchangeable. WebP to PNG is lossless and keeps the alpha channel, so it is the right choice when an image has to go somewhere that does not understand WebP — a desktop application, an office document, most print workflows. WebP to JPG is the right choice when the destination needs maximum compatibility and the image has no transparency, at the cost of a larger file and a flattened background.
Quality is the only real judgement call. For photographs, 75–82% is where size stops falling much faster than quality; below about 70 you start to see blotching in gradients, and above 90 you pay a great many bytes for a difference nobody will spot.
Resizing and compressing are different operations
Image Resizer changes pixel dimensions. Image Compressor changes how those pixels are encoded. They are not interchangeable, and reaching for the wrong one is the commonest reason a file is still too large afterwards.
Shrinking dimensions is the only one of the two that produces a dramatic reduction, because file size grows roughly with pixel count: halving width and height together leaves a quarter of the pixels. It is also irreversible. The discarded detail is gone, and scaling the result back up interpolates between the pixels that remain instead of recovering anything.
Compression at unchanged dimensions is gentler but weaker. It is the right choice when the image has to stay at an exact size — a hero banner, a thumbnail grid, a passport-photo crop.
iPhone photographs
Since iOS 11 the default camera format has been HEIC, which is high-efficiency video coding applied to still frames. It is roughly half the size of a comparable JPG at similar quality, and it is a real problem outside Apple's ecosystem: Safari displays it, most other browsers will not, and a great many web forms and Windows applications reject the extension outright.
HEIC to JPG and HEIC to PNG decode it in the browser, so a photo never has to be sent to a stranger's converter to become usable. JFIF is a much smaller confusion — an ordinary JPEG written into a container extension by some Windows software and email clients — and JFIF to PNG exists because a surprising number of uploaders refuse the filename rather than the contents.
Animation, and its ceiling
GIF stores eight bits per pixel against a palette of 256 colours chosen per frame. That is why video-derived GIFs band badly in skies and gradients: the source has millions of colours and the destination has 256. It is also why a GIF is frequently larger than the MP4 it came from while looking worse.
Video to GIF and the format-specific MP4, WebM and MOV converters sample frames rather than keeping every one, and lowering the frame rate and the dimensions is what keeps the output usable. Image to GIF goes the other way, assembling a sequence of stills into a loop. If the destination is a website rather than a chat window, an MP4 or WebM inside a video element is both smaller and better looking than any GIF; GIF stays the right answer only where a video tag will not be accepted.
APNG is the other animated format and it has the opposite problem: every browser plays it, and almost nothing else does. Chat applications, markdown renderers and office software read the first frame and ignore the rest, so an APNG that looks fine to you arrives as a still image for most recipients. APNG to GIF fixes that by playing your animation in a hidden element and photographing each frame off a canvas as it passes, then writing a genuine GIF locally — no codec library to download and no server to trust, because your browser already contains the decoder. Two consequences follow from doing it that way. A static PNG is refused rather than turned into a pointless one-frame GIF, and the frame delay has a 20 ms floor, which caps the output at 50 fps. Each frame is quantised to its own 256-colour palette instead of sharing one chosen from the first frame; that costs a little size and stops later scenes drifting in colour.
Base64, and when embedding is a mistake
Image to Base64 turns a file into text so it can be pasted into CSS, JSON or an HTML attribute, and Base64 to Image reverses it. The encoding costs about a third again in size, because three bytes become four characters, and an embedded image cannot be cached separately from the document carrying it or fetched in parallel with other assets.
For a 40 KB photograph that is a poor trade. For a small icon, a favicon or a placeholder that has to arrive with the HTML anyway, it is a good one. The useful threshold is somewhere around a kilobyte or two. Placeholder Image Generator sits at exactly that size, which is why embedding its output is normally sensible.
What PNG to SVG does not do
PNG to SVG wraps raster pixels inside an SVG container. It does not trace outlines, detect shapes or produce editable paths — genuine vectorisation is a hard problem that gives approximate results even when it works. What the wrapper provides is a valid SVG file that SVG-only systems will accept, scaling the container rather than the artwork. SVG to PNG is the honest direction of travel: real vector input, rendered to pixels at 1×, 2× or 4×.
The filename is not what identifies the format
Every converter here reads the first bytes of your file rather than trusting its extension. A PNG begins 89 50 4E 47, a JPEG begins FF D8 FF, a WebP is a RIFF container carrying WEBP eight bytes in, and a GIF begins GIF8. That is why a .jfif, a screenshot someone renamed to .jpg, or a PNG mislabelled by an export script all convert correctly here, and why a file that is genuinely damaged is refused instead of quietly producing garbage output.
Where the processing happens
Every tool above decodes your image with the browser's own image decoder, draws it onto a Canvas, and re-encodes it with toBlob or toDataURL. Those are local APIs; there is no upload endpoint in this codebase for them to reach. A conversion keeps working if your connection drops, the speed limit is your processor rather than a queue, and closing the tab releases the memory. The stated size limit on each tool describes what your device can hold, not what we are willing to store.
