Image Converter & Compressor — Resize, WebP/AVIF, Bulk

Convert and compress images in bulk: JPEG, PNG, HEIC (iPhone), GIF, SVG, TIFF to WebP, AVIF, JPEG, PNG or PDF. Resize, hit a target file size, strip EXIF and GPS, merge images into one PDF, optional ZIP. $2 per 1,000 images.

Convert images to WebP, AVIF, JPEG or PNG, compress them and resize them in bulk. Paste a list of image URLs (JPEG, PNG, WebP, AVIF, HEIC/HEIF iPhone photos, GIF, TIFF or SVG; the format is read from the file itself) and get each one back converted, compressed and optionally resized, with a direct download link and a row showing the file size before and after and the % saved. Set a max width/height (fit inside, crop to cover, or pad to contain), a quality level, or a target file size in KB and the actor lowers the quality, then the dimensions, until each image fits. EXIF metadata, including GPS location, is stripped by default after photos are rotated upright, so you never publish where a photo was taken; each row still tells you whether the original had EXIF or GPS. PNG compression uses palette quantisation, the technique behind TinyPNG, so it works as a bulk TinyPNG alternative with no 20-image limit. Animated GIFs stay animated as WebP, SVGs are rasterised at the size you ask for, and you can download everything as ZIP files. Choose PDF as the output to merge images into one PDF (fit-to-image, A4 or Letter pages, with margins) or make one PDF per image. Use it to compress images for website speed and Core Web Vitals, convert product photos for an e-commerce catalogue, generate thumbnails, prepare images for a CMS or CDN migration, or as an image tool for AI agents and automation pipelines. $2 per 1,000 images with no compute bill on top, versus $10 per 1,000 with the leading converter. Failed and unsupported images are never charged.

What data does it return?

Every run outputs clean, schema-validated rows like these:

fileName	format	width	height	originalFormat	originalBytes	outputBytes	savedPercent	hadGps
00012-AMISOM_Police_Officers_attending_a_briefing.webp	webp	5184	3456	jpeg	6545941	696450	89.4	false
00003-Maharaja_Jagat_Singh_of_Jaipur.webp	webp	960	738	jpeg	276908	138682	49.9	false
00032-EDDI_06wk_19970324.webp	webp	1024	1024	png	285110	99856	65	false
00009-Washington_primary_results_map.webp	webp	810	535	svg	770420	35256	95.4	false

How much does it cost?

Transparent pay-per-event pricing — you only pay for what you get, and the actor always respects your run budget: set a maximum total charge and it stops cleanly at the cap instead of overrunning.

Event	Price	Charged	Worked example
image-processed	$0.002	per output image converted and delivered (resize, compression, metadata stripping, size targeting and ZIP included)	100 images = $0.20; 1,000 images = $2.00; 10,000 images = $20
large-image	$0.002	per source image over 25 megapixels (all frames count for kept animations; added on top of image-processed; up to 50 MP accepted)	A 36 MP camera photo = $0.002 + $0.002 = $0.004; a 12 MP phone photo has no add-on
heic-decoded	$0.001	per HEIC/HEIF source image decoded (iPhone photos; added on top of image-processed)	100 iPhone photos to JPEG = 100 × ($0.002 + $0.001) = $0.30
pdf-created	$0.002	per PDF file created (each page image is also one image-processed)	10 images merged into one PDF = 10 × $0.002 + $0.002 = $0.022; 10 images as 10 separate PDFs = $0.04
apify-actor-start	$0.00005	per run per GB of memory (platform start fee)	One run at 1 GB = $0.00005

Input options

Field	Type	Required	Default	Description
imageUrls	array	yes	—	Direct links to the images to convert (JPEG, PNG, WebP, AVIF, HEIC/HEIF from iPhones, GIF, TIFF or SVG; the format is detected from the file itself). Up to 25 MB and 50 megapixels per image. To convert every image on a web page, collect the links first with our Bulk Image Downloader.
format	string	no	"webp"	WebP is the best all-round choice for websites (about 25-35% smaller than JPEG). AVIF is smaller still but slower to encode. JPEG is the most compatible (e.g. for iPhone HEIC photos). PDF puts the images into a PDF document (see the PDF options below). 'Keep' re-compresses each image in its own format (SVG becomes PNG, HEIC becomes JPEG).
quality	integer	no	80	Lower = smaller files. 75-85 is visually lossless for most photos. For PNG, anything below 100 reduces the colour palette (the TinyPNG technique); 100 = lossless.
width	integer	no	—	Resize so the image is at most this wide. Empty = keep the original width. Images are never enlarged.
height	integer	no	—	Resize so the image is at most this tall. Empty = keep the original height.
fit	string	no	"inside"	When both width and height are set: 'inside' keeps the aspect ratio within the box, 'cover' crops to fill the box exactly, 'contain' pads to the box with the background colour.
background	string	no	"#ffffff"	Hex colour used for padding ('contain') and for transparent areas when converting to JPEG.
stripMetadata	boolean	no	true	Remove EXIF, GPS location, camera details, XMP and IPTC from the output (photos are rotated upright first). Smaller files and no leaked locations. Each row still reports whether the original had EXIF / GPS.
maxFileSizeKb	number	no	—	Optional. Lowers the quality step by step (and, if needed, the dimensions) until each image fits under this size. Rows show the quality used and whether the target was met.
keepAnimation	boolean	no	true	Animated GIF or WebP converted to WebP keep all frames. Off = first frame only. AVIF, JPEG and PNG output always use the first frame.
outputMode	string	no	"links"	'Links' saves each image with its own download link. 'ZIP' bundles all images into ZIP files (up to 200 MB each; links in the OUTPUT record). 'Both' does both. A merged PDF is always a download link.
filenamePattern	string	no	"{index}-{name}"	Tokens: {index} (00001…), {name} (original file name), {width}, {height}, {format}. The extension is added automatically; duplicate names get a -2, -3… suffix.
maxImages	integer	no	1000	Stop after converting this many images.
pdfMode	string	no	"merge"	'Merge' puts all images into one PDF, one image per page, in the order of your list. 'Separate' makes one PDF per image.
pdfPageSize	string	no	"fit"	'Fit image' makes each page exactly the size of its image (96 dpi). A4 and Letter pages turn portrait or landscape to match each image, which is scaled to fill the page inside the margin.
pdfMarginMm	integer	no	10	White margin around the image on A4 and Letter pages. 'Fit image' pages have no margin.
pdfFileName	string	no	"images"	Name of the merged PDF (without .pdf). Very large merges are split into parts: name.pdf, name-part-2.pdf, ...

Limits & honest notes

• Input: direct image URLs. To convert every image on a web page, collect the links first with our Bulk Image Downloader and pass them in.
• Each source image can be up to 25 MB and 50 megapixels (animations up to 100 MP across all frames). Larger files are reported as errors and not charged.
• Sources over 25 megapixels cost a second large-image event ($0.002), because they take far more compute. Everyday photos (12-24 MP phone pictures) are not affected.
• Supported inputs: JPEG, PNG, WebP, AVIF, HEIC/HEIF, GIF (incl. animated), TIFF and SVG. BMP and ICO are not supported and are reported as errors (not charged).
• HEIC/HEIF (iPhone photos): the primary image of each file is converted (bursts and multi-image files give one image), upright as the phone displays it, with Display P3 colours converted to standard sRGB. EXIF from HEIC files is not copied to the output even with metadata stripping off (the colour profile is). HEIC decoding is slower, so it adds a heic-decoded event ($0.001); for 48 MP HEIC photos run with 2 GB of memory or more.
• PDF output: one image per page, in the order of your list. Photos are embedded as JPEG at your quality setting, PNG/GIF/TIFF/SVG as lossless PNG so text stays sharp. Merged PDFs larger than about 128 MB (at 1 GB memory) are split into parts. PDF output ignores the ZIP option when merging.
• Animation is kept for GIF/WebP to WebP; AVIF, JPEG and PNG output use the first frame. SVGs are rasterised; references to external files or URLs inside an SVG are never loaded.
• Images are never enlarged beyond their original size. Converting to JPEG fills transparent areas with the background colour (default white).
• A target file size is a best effort: if an image can't reach it at minimum quality after one resize, it is delivered as small as possible and the row says targetMet: false.
• Stripping metadata also converts colours to standard sRGB. Turn stripping off to keep EXIF, ICC colour profiles, XMP and IPTC.
• Download links work for the lifetime of the run's storage (Apify's default retention for your plan). ZIP files are split into parts of up to 200 MB.
• Internal and private network addresses are always refused, including through redirects or DNS tricks. Only convert images you have the right to use.
• Respects your run budget: set a maximum total charge and the actor stops cleanly at the cap.
